Do the poor spend a different amount of time in the shower than the rich? The results of a survey asking poor and rich people how many minutes they spend in the shower are shown below. Assume both populations are normally distributed and average 1 is the average number of minutes that the poor spend in the shower. Poor 13 6 10 12 14 15 5 17 Rich: 10 9 6 20 15 18 19 4 12 17 15 Assume both follow a Normal distribution. Perform a hypothesis test and use a .01 level of significance. Round all answers to 4 places where possible. Step (1) Determine the null and alternative hypotheses. Ho: #1 Ha: ul Step (2) Determine the test statistic and p-value. Test Statistic: tv - -1 1391 p -value - 0.1273
