A company that makes fleece clothing uses fleece produced from two farms, northern farm and
western farm. Let W equal the total weight of fleece from 10 randomly selected sheep from northern
farm and 15 randomly selected sheep from western farm. Which of the falling is the standard
deviation, in pounds, of W? ✔Correct Answer--C) √(10(1.3)^2+15(0.5)^2)
A roadrunner is a desire bird that tends to run instead of fly. Suppose a roadrunner has a total length
of 59.0 cm and tail length on 31.1 cm. based on the residual, does the regression model overestimate
or underestimate the tail length of the roadrunner? ✔Correct Answer--A) Underestimate, because
the residual is positive
A car rental agency has two locations in a city. The box plots below summarizes the miles driven for
one day of a single-day car rentals at each location. Based on the box plots, which statement
provides the best comparison of the two locations? ✔Correct Answer--C) Compared with location
A, the miles driven for location B display more variability and the median is greater
Research indicates that the standard deviation of typical human body temperature is 0.4 degree
Celsius (C). Which of the following represents the standard deviation of typical human body
temperature in degrees Fahrenheit (F), where F=9/5C + 32? ✔Correct Answer--B) 9/5(0.4)

First-year students enrolled at a college were asked whether they play video games. The responses,

shown in the table. Of all the students enrolled in the school of arts who responded, approximately
what proportion responded that they play video games? ✔Correct Answer--C) 0.438
The height and age of each child in a random sample of children were recorded. The value of the
correlation coefficient between height and age for the children in the sample was 0.8. Based on the
least-squares regression line created from the data to predict the height of a child based on age,
which of the following is a correct statement? ✔Correct Answer--C) The proportion of the variation
in height that is explained by a regression on age is 0.64
The results of 1,000 trials of the simulation are shown in the histogram. Based own the results of the
simulation, is there convincing statistical evidence at the significance level of 0.05 that the event of
Audrey selling at least 7 of the 30 selected tickets is unlikely to have occurred by the chance alone?
✔Correct Answer--E) No, because the simulation suggests that Audrey selling at least 7 of 30
selected tickets would occur about 13.8% of the time.
