An analyst wants to know if there was a significant difference in the average number of hours worked per week from 2000 (Group 1) to 2004 (Group 2). They gathered all the data from the General Social Survey and listed the following summary statistics from the sampling: The General Social Survey uses a method similar to simple random sampling. Year 2000 2004 Mean 38.95 38.34 Std. Dev. 12.22 16.32 Unweighted n Source: General Social Survey (sda.berkeley.edu) Choose the correct p-value for a significance level with an alpha level of 0.05. 0.6643 0.0821 0.0532 0.8210

A study evaluated the weekly time (in hours) that men and women spent in employment. The software shows the following results: Gender N Mean StDev SE Mean Men 4253 31.4 22.6 0.3465 Women 6766 18.9 20.0 0.2431 Difference = μMEN - μWOMEN 95% CI for difference: (11.67, 13.33) T-Test of difference = 0 (vs not =): T-value = 29.53 P-value = 0.000 What is the value of the estimated difference between the two population means that we see in the sample?

When 583 female workers in the 2012 GSS were asked how many hours they worked in the previous week, the mean was 37.0 hours, with a standard deviation of 15.1 hours. Does this suggest that the population mean work week for females is significantly different from 40 hours? Answer by: (10 points) A) Identifying the relevant variable and parameter B) Stating the null and alternative hypotheses C) Reporting and interpreting the p-value for the test statistic value D) Explaining how to make a decision for the significance level of 0.01.

A past study it is assumed that adults in America spent an average of 18 hours a week on leisure activities. A researcher claims that the average amount of time spent on leisure activities has changed. She took a random sample of 12 adults and asked them about the time they spent per week on leisure activities. Their responses (in hours) are as follows: 13.6 14.0 24.5 24.6 22.9 37.7 14.6 14.5 21.5 21.0 17.8 21.4 Assume that the time spent on leisure activities by all adults are approximately normally distributed. Does this data support the researcher's claim? using level of significance α = 0.1, carry out a hypothesis test.
