Imagine you wish to determine whether the mean number of hours worked per week by women in a sample differs from the national 40-hour average. Use this information and the table below to test your hypothesis. Weekly Hours Worked Women Range 60 Minimum value Maximum value 65 Mean 41.5 Standard deviation 10.00 Number of observations 1 1 - Make three necessary assumptions.

Try yourself 9.2 The 40-hour work week did not become a U.S. standard until 1940. Today, many white-collar employees work more than 40 hours per week because management demands longer hours or offers large monetary incentives. A random sample of white-collar employees was obtained, and the number of hours each worked during the last week are given in the following table. 44.7 42.0 45.8 43.0 42.8 50.9 47.0 41.9 49.3 45.6 45.7 39.4 39.0 44.4 Is there any evidence the...

23. Wu's job pays $12/hour, and requires him to be at work at least 40 hours/week. He is allowed to work as much overtime (hours > 40/week) as he wants, and overtime pays "time-and-a-half" for hours worked > 40/week and < 60/week, and "double time" for hours worked > 60/week. He earns no weekly endowment. What is the vertical value of the vertical intercept for Wu's choice (Leisure, $) bundles for a typical 168 hour week? set over

Many college graduates who are employed full-time have longer than 40-hour work weeks. Suppose that we wish to estimate the mean number of hours, u, worked per week by college graduates employed full-time. We'll choose a random sample of college graduates employed full- time and use the mean of this sample to estimate u. Assuming that the standard deviation of the number of hours worked by college graduates is 6.30 hours per week, what is the minimum sample size needed...

Some college graduates employed full-time work more than 40 hours per week, and some work fewer than 40 hours per week. We suspect that the mean number of hours worked per week by college graduates, A. is greater than 40 hours and wish to do a statistical test. We select a random sample of college graduates employed full-time and find that the mean of the sample is 44 hours and that the standard deviation is 4 hours Based on this...

Some college graduates employed full-time work more than 40 hours per week, and some work fewer than 40 hours per week. We suspect that the mean number of hours worked per week by college graduates, , is different from 40 hours and wish to do a statistical test. We select a random sample of college graduates employed full-time and find that the mean of the sample is 36 hours and that the standard deviation is 3 hours. Based on this...

It seems these days that college graduates who are employed full-time work more than 40-hour weeks. Data are available that can help us decide if this is true. A survey was recently sent to a group of adults selected at random. There were 15 respondents who were college graduates employed full-time. The mean number of hours worked per week by these 15 respondents was 45 hours, with a standard deviation of 9 hours. Assume that the population of hours worked...
