Chapter 3.A, Problem 50E
Population Comparison. Between the 2010 U.S. census and 2011 (one year later), the official population of Denver increased from 600,158 to 619,968, during the same period the population of San Antonio increased from 1,327,407 to 1,359,758. Which city had the greater absolute change in population? Which city had the greater relative change in population?

Show a clear, step-by-step solution.
A study was done using a treatment group and a placebo group. The results are shown in the table. Assume that the two samples are independent simple random samples selected
from normally distributed populations, and do not assume that the population standard deviations are equal. Complete parts (a) and (b) below. Use a 0.05 significance level for both
parts.
a. Test the claim that the two samples are from populations with the same mean.

- A study of seat belt users and nonusers yielded the randomly selected sample data summarized in the accompanying table. Use a 0.05 significance level to test the claim that the amount of smoking is independent of seat belt use.

Construct a scatterplot, find the value of the linear correlation coefficient r, and of r. Determine whether there is sufficient evidence to support a claim of linear correlation between the two variables. Should we expect that there would be a correlation?

- A data set includes data from student evaluations of courses. The summary statistics are n = 93, x=3.83, s = 0.68. Use a 0.10 significance level to test the claim that the population of student course evaluations has a mean equal to 4.00. Assume that a simple random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. What are the null and alternative hypotheses? OA.
