identify hypotheses.Write the null and alternative hypotheses in words and then symbols foreach of the following situations.(a) A tutoring company would like to understand if most students tend to improve their grades(or not) after they use their services. They sample 200 of the students who used their servicein the past year and ask them if their grades have improved or declined from the previousyear.(b) Employers at a firm are worried about the effect of March Madness, a basketball championship held each spring in the US, on employee productivity. They estimate that on a regular businessday employees spend on average 15 minutes of company time checking personal email, makingpersonal phone calls, etc. They also collect data on how much company time employees spendon such non-business activities during March Madness. They want to determine if these dataprovide convincing evidence that employee productivity changed during March Madness.(c) Since 2008, chain restaurants in California have been required to display calorie counts ofeach menu item. Prior to menus displaying calorie counts, the average calorie intake of dinersat a restaurant was 1100 calories. After calorie counts started to be displayed on menus,a nutritionist collected data on the number of calories consumed at this restaurant from arandom sample of diners. Do these data provide convincing evidence of a difference in theaverage calorie intake of a diners at this restaurant
Answer:
H0 : μ = 0 ; H1 : μ > 0 ;
H0 : μ = 15 ; H1 : μ ≠ 15
H0 : μ = 1100 ; H1 : μ ≠ 1100
Step-by-step explanation:
Null hypothesis H0 : mean grade of student after they use service of tutoring company is the same.
H0 : μ = 0
Alternative hypothesis H1 : mean grade of student after using service of the tutoring company increases
H1 : μ > 0
2.)
Null hypothesis H0 : Average or mean company time spent checking personal is 15 minutes
H0 : μ = 15
Alternative hypothesis H1 : Average or mean company time spent checking personal mail is not equal to 15 minutes
H1 : μ ≠ 15
C.)
Null hypothesis H0 : Average calorie intake of diner at restaurant.
H0 : μ = 1100
Alternative hypothesis H1 : There is a difference in average calorie intake of diner at restaurant.
H1 : μ ≠ 1100

if you were a doughnut shop owner and wanted to find out which doughnut you should make more of, which measure of central tendency would you use.
Answer:
Mode
Step-by-step explanation:
Measures of central tendency:
The 3 most common measures of central tendency are: The mean, the median, and the mode.
The mean is the average value.
The median separates the lower 50% of the values from the upper 50% of the values.
The mode is the value that appears the most times in the data-set.
In this question:
To find the doughnut you should make more, you should have to know which has the biggest interest from clients, that is, the one that is sold the most, which means that the mode should be used.
Answer:
Mode

(1 p 18. Demarcus drew a pair of complementary angles. He drew one angle that had a measure of 48º. What was the measure of the other angle he drew? 42° 48° O 132° O 138°
Answer: 42
Step-by-step explanation:
Complementary angles are angles in which the sums equal 90.
90 - 48 = 42.
what is the measurement of jkl
Answer:
The angles combined together are 200, so you will have to subtract the difference of 200 and 180 from the combined angles. The angle of line JKL is 160 degrees.
Step-by-step explanation:
Please mark as brainliest!
Answer:
The measure of angle JKL is 97 degrees.

You are selling lemonade. You find that if you set the price at $2.00 per cup, you sell 14 cups over the
course of a day. You also notice that for every $0.10 you decrease the price by, you sell 3 more cups over
the course of the day. Come up with a linear equation to model this situation.
Step-by-step explanation:
$2.00x-($.10x)=3+x
the x would stand for cups and since you already get 3 more cups in a day than before then you would put 3+x_how many cups you sell. the $2.00 is for how much money each up is. and the -$.10 is subtracting 10 cents for each cup you sell.
I dont know if this is correct but this is how I would make my equation

What is the area of the shaded region?
A. 3/5 sq ft
B. 5/16 sq ft
C. 5/24 sq ft
D. 3/20 sq ft
Answer:
B- 5/16 sq ft
Step-by-step explanation:
Their are 48 tiles total
15/48 are shaded so,
48 and 15 both go into 3,
15÷3= 5
48÷3=16
So then answer would be 5/16 sq ft
PLEASE HELP!! The AHS Football team did a weigh in at the start of training camp. The weights of the players were distributed normally with a mean of 98kg and a standard deviation of 6kg. Which of the following curves represents the data? A,B, Or C??
Answer: Choice C
=========================================================
Explanation:
The mean is 98, so that's the center of the distribution. This is where the highest point occurs because the most people are clustered around here. This rules out choice A and the answer is between B or C.
One standard deviation above the mean is 98+6 = 104. All we do is add on the standard deviation (6) to the mean (98) to get 104.
One standard deviation below the mean is 98-6 = 92
The graph that has tickmarks at 92 and 104 indicate we are exactly 1 standard deviation from the mean (98)
Similarly, 2 standard deviations above the mean is at 98+2*6 = 98+12 = 110. Or you could say 104+6 = 110.
2 standard deviations below the mean would get us to 98-2*6 = 98-12 = 86
The same idea applies to 3 standard deviations as well.
All of this matches with graph C. We can eliminate graph B by noticing that something like 95 is not a result of 98-6.

D
Reasonable. The pears and apples is about 3 cups and the grapes and oranges is exactly 2 cups.
Answer:
A.
Step-by-step explanation:
Not reasonable, Why did you put that as your answer?
The whole numbers add up to more then 4 cups.
