Answers
Answer:
Thanksgiving, median = 17
New year's eve, median = 8
Thanksgiving, IQR = 12
New year's eve, IQR = 10
THANKSGIVING has greater variability
Step-by-step explanation:
The median value of a box plot is the line which lies in the middle of the box :
From the plot, the best estimate :
Thanksgiving, median = 17
New year's eve, median = 8
THE Interquartile range, IQR is the difference between the upper quartile and lower quartile values, Q3 - Q1 ;
Lower quartile = the starting point of the box
Upper quartile = the endpoint of the box
From the plot ; Best estimate :
Thanksgiving :
Q1 = 12 ; Q3 = 24
IQR = Q3 - Q1 = 24 - 12 = 12
New year's eve :
Q1 = 5 ; Q3 = 15
IQR = Q3 - Q1 = 15 - 5 = 10
Thanksgiving :
Range = Maximum - Minimum
Range = (29 - 5) = 24
New year's eve:
Range = Maximum - Minimum
Range = 22 - 3 = 19
Hence, Thanksgiving has greater variability

1. We would like to know if Intel's stock and Southwest Airlines' stock have similar rates of return. To find out, we take a random sample of 50 days for Intel's stock and another random sample of 50 days for Southwest's stock.

b. Not Paired
2. We randomly sample 50 items from Target stores and note the price for each. Then we visit Walmart and collect the price for each of those same 50 items.

3. A school board would like to determine whether there is a difference in average SAT scores for students at one high school versus another high school in the district. To check, they take a simple random sample of 100 students from each high school.
a. Paired
b. Not Paired
Answers
Answer:
1. Can be Paired or Not Paired
2. Paired
3. Not Paired
Step-by-step explanation:
Two sets of observations are paired if each observation in one set has a special correspondence or connection with exactly one observation in the other data set.
1. Can be Paired or Not paired
Reason -
We might look at testing the difference of means using a two sample t-test. However, we may also try running a paired t-test.
But its used in cases where the observations are usually from the same populations at different times or through different sources etc.
Hence can't conclude that it is paired or not paired.
2. Paired
Reason -
Each record is a price of the same item from different stores.
3. Not paired
Reason -
This is again a case of testing the difference of means of two-samples (2 independent samples precisely) that are not paired.
1. Can't conclude paired or not paired
2. Paired
3. Not Paired
What do you mean by paired or unpaired?Two sets of observations are said to be paired if each observation in one data set has a specific connection with exactly one observation in the other data set otherwise it is unpaired.
1. Can't conclude paired or not paired because It may look at testing the difference of means using a two-sample test, But it's used in cases where the observations are from the same populations at different times or through various sources, etc.
2. Paired because each item is the price of the same item from different stores.
3. Not paired because in this case of testing the difference of means of two independent samples that are not paired.

Three people take 2 1⁄2( two and a half ) hours to deliver leaflets to 270 houses
Assuming all people deliver leaflets at the same rate, how long will it take five people to deliver leaflets to 450 houses?
Give your answer in hours and minutes
Answers
9514 1404 393
Answer:
2 hours 30 minutes
Step-by-step explanation:
Effort is measured in people-hours per house. Here, the effort to deliver one leaflet is ...
(3 people)(2.5 hours)/(270 houses) = 1/36 people-hours/house
Then the number of hours (h) for 5 people and 450 houses is ...
(5 people)(h hours)/(450 houses) = 1/36 people-hours/house
h = (1/36)(450/5) = 2.5
It will take 2 hours 30 minutes to deliver to 450 houses.
_____
Alternate solution
The time is (assumed) inversely proportional to the number of people, so increasing the number of people from 3 to 5 multiplies the time by 3/5. The time is proportional to the number of houses, so increasing the number of houses from 270 to 450 multiplies the time by 450/270 = 5/3. The time for the second task is (3/5)(5/3) = 1 times the time for the first task.
2 1/2 hours is 2 hours 30 minutes.

As part of a study of corporate employees, the director of human resources for PNC, Inc. wants to compare the distance traveled to work by employees at its office in downtown Cincinnati with the distance for those in downtown Pittsburgh. A sample of 40 Pittsburgh employees showed they travel a mean of 370 miles per month. A sample of 35 Cincinnati employees showed they travel a mean of 380 miles per month. Do the Cincinnati employees travel the same distance to work, on average, as the Pittsburgh employees
Answers
Answer:
Both groups of Employees do not travel the same distance to work hence we will reject the Null hypothesis
Step-by-step explanation:
40 Pittsburgh employees mean travel time = 370 miles
35 Cincinnati employees mean travel time = 380 miles
Both groups of Employees do not travel the same distance to work hence we will reject the Null hypothesis
H0 : μ1 = μ2
H1 : μ1 ≠ μ2
mean = total distance / Number of employees
For Pittsburgh
370 = x / 40
x = 370 * 40 = 14,800 miles
For Cincinnati
380 = y / 35
y = 380 * 35 = 13,300 miles
