A sugar box manufacturing company is accurately making 100 g packets. Suppose a business researcher randomly selects 100 boxes, weighs each of them and computes its mean. Due to non-random selection or by chance, a researcher selects packets that have not been adequately filled and that is how he gets the mean weight of 98 g, which falls in the rejection region. The decision is to reject the null hypothesis even though the population mean is actually 100 g. Which kind of error has the researcher done in this case
Answer:
The kind of error the researcher has done is a;
Type I error
Step-by-step explanation:
When carrying out hypothesis testing in statistical analysis, a type I error is the type of error said to have occurred when a null hypothesis that is true or correct is rejected which is a false positive conclusion
Given that that sugar box manufacturing company makes the boxes to be 100 g accurately, and that the researcher makes non-random or randomly selects packets which are not filled, the mean of the filled packets is expected to be 100 g making the conclusion for rejection of the null hypothesis a false positive rejection

Does the line passing through the points (3, 3) and (7, 11) intersect the line passing through the points (5, 8) and (13, 24
Answer:
I understand why you are asking about this Ammaria, these type of questions take a lot of understanding of graphing. Please feel ok asking me questions :)
Step-by-step explanation:
we are given two points
P1 = (3,3) in the form (x1,y1)
P2 = (7,11) in the form (x2,y2)
slope = m
m = (y2-y1) / (x2-x1)
m = (11-3) / (7-3)
m = 8 / 4
m = 2
now use the slope along with one of the given points, either one will work, i'll use P1 , and put that into the point-slope formula.
y-3 = 2(x-3)
y -3 = 2x -6
y = 2x -3
So with the above formula we can check to see if the points work by plugging them into the formula.
P3 = (5,8)
8 = 2(5) - 3
no point 3 does not work so it's not on the line
P4 = (13, 24)
24 = 2(13) - 3
no point 4 does not work either.
Without looking, Luke picks necklace beads from a bag of 52 beads. Half the beads are rough. The other half are smooth. There are 13 red beads, 13 blue beads, 13 green beads, and 13 black beads.
What is the theoretical probability of selecting a blue bead? Write the probability as a fraction in simplest form.
Answer: [tex]\dfrac{1}{4}[/tex]
Step-by-step explanation:
Given
The total no of beads is 52
there 13-red,13-blue,13-green, and 13-black
favorable outcomes to select a blue bead is 13
Total outcomes are 52
Probability is given by
[tex]P=\dfrac{\text{favorable}}{\text{Total outcomes}}\\\\\Rightarrow P=\dfrac{13}{52}=\dfrac{1}{4}[/tex]
Answer: 1/4

To find Radius of sphere S we multiply 1/5 by 500.
1/5 x 500 = 100
We now have the radius of sphere S. Now we use the formula for a sphere and we get our answer.
4/3 \pi 100^2 = 4188790.205

Answer:
X=-2
Step-by-step explanation:
1. Open up the brackets
You then get
6+8x+12=2
2. Send the whole numbers to the other sides
8x= 2-6-12
8x = - 16
3. Divide both sides by 8 to leave x alone
X=-2

bill js a builder. On Monday he msde mortar mix. he used 24kg of sand and 5kg of cement. on tuesday bill will make the same type of mortar mix. he will use 36kg of sand. how much cement does he need to make the same type of mortar mix?
Answer: 7.5kg
Step-by-step explanation:
Since Bill made mortar mix and he used 24kg of sand and 5kg of cement. This means that for 1 kg of cement, (24/5) = 4.8 kg of sand is used.
Therefore, when he uses 36kg of sand, the kg of cement used will be:
= 36 / 4.8
= 7.5 kg
Therefore, he'll use 7.5kg of cement and 36kg of sand.

please help me with these two problems
Problem 1
With mean = median, the data set is symmetrical. Well it's more accurate to say "roughly symmetrical" due to the phrasing "mean is approximately equal to the median". Using the median as its center is fairly common with many distributions, so there isn't an issue here.
The error is from the phrasing "the quartiles should be used to measure the spread". The quartiles themselves don't measure spread. They are simply single data points and do not tell us the spread. If Ralph said Q3 = 75 is a measure of spread, then he would be incorrect. However, the difference between the third and first quartile will help get the IQR (interquartile range), as described by this equation below
IQR = Q3 - Q1
and this is one tool to measure how spread out data is. The larger the IQR is, the more spread out the data will be.
The IQR is how far of a gap it is from Q1 to Q3. Another tool to measure spread is the standard deviation. Ralph was probably thinking about the IQR when he mentioned the quartiles, but he should be more specific about what he means.
=======================================================
Problem 2
Answer: Skewed left
This is the same as saying "negatively skewed"
---------------
Explanation:
The main cluster of values is on the right side, while a small portion of values are to the left. We consider this the left tail and the left tail is pulled longer compared to the right tail. The further left we go, the shorter the bar and eventually we hit outliers. These much smaller outliers compared to the main cluster pull on the mean to make it smaller than it should be.
One example could be that this curve represents test scores. The majority of the class could get in the range of say 70 to 90. Then there's the unfortunate few outliers who scored much lower (possibly 40 through 60); those outlier scores pull down the mean grade of the class overall.
In short, negatively skewed data indicates that mean < median.

What is the area of the triangle shown below
Given:
The triangle is a right angle triangle
Height of triangle = 3 m
Hypotenuse of triangle = 5 m
To find:
Area of triangle
Steps:
To find the area of a triangle we have multiply the base and height of triangle into 1/2, but the figure doesn't show the measurements of the base, so we have to use Pythagoras theorem to find the third side this triangle is a right angle triangle.
A² + B² = C²
3² + B² = 5²
9 + B² = 25
B² = 25 - 9
B² = 16
B = √16 = 4 m
Therefore the base length of the triangle is 4 m
Now we can find the area of the triangle
Area of triangle = (Base × Height)1/2
Area of triangle = (4 × 3)1/2
Area of triangle = 12 × 1/2
Area of triangle = 6 m²
Therefore the area of the triangle is B) 6 meters square
Happy to help :)
If you have any doubts, pls ask
What is the area of the front face?
Answer:
the area of the front face would be 40 square inches.
Step-by-step explanation:
to find the are of a rectangle, you multiply the length times the width. we can see that the length is 8 inches at the bottom of the front face and we can see that width is 5 inches next to the left side face. if we take those two numbers (5 and 8) and multiply them, we get 40. all you have to do after that is add "square inches" to the end because when you find the area of something, it will be squared and the measurement used in inches.
Jenae noticed that many of her co-workers would opt for the coffee that appeared to be most recently brewed, regardless of the flavor of the coffee offered. This leads her to believe that what she was witnessing was not really representative of everyone's true flavor preferences. She adapted her experimental study accordingly. Select one control in Jenae's experimental study.
A. Jenae monitors the habits of the co-workers who do not drink coffee.
B. Jenae places condiments at random places throughout the kitchen.
C. Jenae takes note of the frequency in which co-workers refill their coffee mugs.
D. Jenae keeps the same amount of sugar and artificial sweetener at each location.
Answer:
D. Jenae keeps the same amount of sugar and artificial sweetener at each location.
Step-by-step explanation:
Experimental studies are those studies that are based upon the experiments in this the group could be controlled and testable also so according to the given situation, the option D is correct as Jenae have the similar maount of sugar and sweetener at each and every location
Therefore the last option is correct
Answer:
Jenae keeps the same amount of sugar and artificial sweetener at each location.
