Consider this example on how different a median can be from a sample. Suppose there is a company that mentions the average salary at Company A last year was $ 135,750 per year. Being interested in this you try to investigate this. You discover there are 8 individuals, including the business owner, that works at the company. You discover that the salaries of the 7 individuals are surprisingly low. The salaries of those 7 individuals are $8,000, $8,000, $7,000, $11,000, $15,000, $17,000, and $20,000. You then discover the salary of the business owner to be $1,000,000.

Given the data :
8000, 8000, 7000, 11000, 15000, 17000, 20000, 1000000.
Mean = Σx / n = 1086000 / 8 = 135750
Median = 1/2(n+1)th term = 8000
The lower quartile :
Q1 = 1/4(n+1)th term
Q1 = 8000
Q3 = 3/4 (n+1)th term
Q3 = 18500
IQR = 18500 - 8000 = 10500
OUTLIER :
8000 - (1.5*(10500)) = - 7750
18500 + (1.5*(10500)) = 34250
10% trimmed mean
10% * 8
Cut off 1 from the top and bottom
Data becomes : 8000, 8000, 11000, 15000, 17000, 20000
Trimmed mean = 13166
A bakery sells cakes, cookies, and pastries. They wonder if customers are equally likely to buy each product. They take a sample of 200 recent purchases and record what was purchased (they are willing to treat this as a random sample). Here are the results
Product Cakes Cookies Pastries
Observed purchases 65 68 67
They want to perform a x^2 goodness-of-fit test to determine if these results suggest that one type of product is more popular than the others. What is the expected count of cake purchases?
Answers
Answer:
66.667 cakes
Step-by-step explanation:
The expected count or value in a goodness of fit test is the product of the expected percentage and the total count or sample size.
Since the samples are being treated as a random sample, hence, the expected percentage of each of cake, pastries and cookies is the same.
The expected count of cakes is :
100/3 % * sample size
33.3333% * 200
= 66.667 cakes
Caroline weighs 41,390,000 milligrams and her baby sister weighs 3,415 grams. What is their total weight in kilograms?
A. 4.4805 kg
B. 448.05 kg
C. 44.805 kg
D. 4480.5 kg
Answers
Answer:
C. 44.805
Step-by-step explanation:
41,390,000 milligrams is 41.39 in kilograms and then 3,415 grams in kilograms is 3.415 so add those up 41.39+ 3.415= 44.805kg
The total weight in kilograms is C. 44.805 kg
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Convert mg to kg;
Caroline weighs 41,390,000 mg
1 mg = 0.000001 kg
41,390,000 mg = x
x = 41,390,000 mg × 0.000001 kg
= 41.39 kg
Now, Converting her baby sister's weight to kg
1000g = 1 kg
3415 g = x
Cross Multiply;
1000x = 3415g × 1 kg
x = 3415g × 1 kg/1000
x = 3.415 kg
Therefore, the total weight in kilograms is;
41.39 kg + 3.415 kg
= 44.805 kg

Compare the result to the actual standard deviation.
The estimated standard deviation is________(within 0.5 of, over 0.5 less than, over 0.5 greater than) the actual standard deviation. Thus, the estimated standard deviation_________(is, is not) substantially different from the actual standard deviation.
Answers
Answer:
Within 0.5 of ;
is not ;
Step-by-step explanation:
Given the data:
The actual standard deviation, = 1
;
The range rule of thumb to estimate the value if standard deviation is ;
Estimated standard deviation = Range / 4
The range = (maximum - minimum) values
The estimated standard deviation = 4 / 4 = 1
Hence, the estimated standard deviation is with 0.5 of the actual standard deviation, Thus, the estimated standard deviation is not substantially different from the actual standard deviation.

How much work is done lifting a 35 pound object from the ground to the top of a 25 foot building if the cable used weighs 2.5 pounds per foot
Answers
Answer:
3400 ft-lbs
Step-by-step explanation:
The Workdone in lifting the rope :
Number of feet = x
Distance = 25 feets
2.5x + 35
Taking the integral :
∫2.5x + 35 dx at x = 40
Integrating, we have :
1/2(2.5x² ) + 35x at x = 40
1/2(2.5(40)²) + 35(40)
1/2(4000) + 1400
2000 + 1400
= 3400
Hence, Workdone in lifting the rope = 3400 ft-lbs
Belle will randomly select two cards without replacement what is the probability that both will choose two hearts
Answers
The probability that Belle will select two hearts is 2/15.
To find the probability of Belle selecting two hearts, we need to calculate the probability of selecting a heart on the first draw and then, given that the first card was a heart, the probability of selecting another heart on the second draw.
Total number of cards = 3 (star cards) + 4 (hearts cards) + 3 (spade cards) = 10 cards
Probability of selecting a heart on the first draw = 4 (hearts cards) / 10 (total cards) = 2/5
After selecting a heart on the first draw, there will be 9 cards remaining, with 3 hearts cards left.
Probability of selecting a heart on the second draw, given that the first card was a heart = 3 (hearts cards) / 9 (remaining cards) = 1/3
To find the probability of both events happening (selecting two hearts), we multiply the probabilities:
Probability of selecting two hearts = (2/5) x (1/3) = 2/15
Therefore, the probability that Belle will select two hearts is 2/15.

Answer:
1328.4 square units
Step-by-step explanation:
The total surface area is the sum of the areas of the trapezoidal bases, and the areas of each of the four rectangular faces.
The area of each trapezoidal base is ...
A = 1/2(b1 +b2)h
A = 1/2(10 +24)(9) = 153 . . . . square units
__
The total area of the four rectangular faces is ...
A = bh . . . . area of one face
A = 11.4(18) +10(18) +11.4(18) +24(18) = (11.4 +10 +11.4 +24)(18) = 1022.4
So, the total area is ...
SA = 2×base area + face area
= 2×153 +1022.4 = 1328.4 . . . . square units
