A 2013 poll found that 24% of Chinese adults see crime as

a very big problem, and the standard error for this estimate, which can reasonably be modeled
using a normal distribution, is SE = 1:8%.57 Suppose an issue will get special attention from the
Chinese government if more than 1-in-5 Chinese adults express concern on an issue.

(a) Construct hypotheses regarding whether or not crime should receive special attention by the
Chinese government according to the 1-in-5 guideline.
(b) Discuss the appropriateness of using a one-sided or two-sided test for this exercise. Consider:
for this decision process, would we care about one or both directions?
(c) Should crime receive special attention? Use a hypothesis test to justify your answer.

It appears that people who are mildly obese are less active than leaner people. one study looked at the average number of minutes per day that people spend standing or walking. among mildly obese people, the mean number of minutes of daily activity (standing or walking) is approximately normally distributed with mean 376 minutes and standard deviation 64 minutes. the mean number of minutes of daily activity for lean people is approximately normally distributed with mean 528 minutes and standard deviation 107 minutes. a researcher records the minutes of activity for an srs of 7 mildly obese people and an srs of 7 lean people. use z-scores rounded to two decimal places to answer the following: what is the probability (image for it appears that people who are mildly obese are less active than leaner people. one study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 mildly obese people exceeds 420 minutes? what is the probability (image for it appears that people who are mildly obese are less active than leaner people. one study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 lean people exceeds 420 minutes?

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y < 4x − 8 y is greater than or equal to negative 5 over 2 times x plus 5 part a: describe the graph of the system, including shading and the types of lines graphed. provide a description of the solution area. (6 points) part b: is the point (5, −8) included in the solution area for the system? justify your answer mathematically. (4 points)
