Hypothesis testing for a difference of 2 mean (independent)

6/25/2021 MyOpenMath Do the poor spend more 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. Poor 37 11 23 19 10 30 37 37 40 33 12 16 10 Rich: 20 6 4 25 20 23 19 18 18 25 21 12 21 Assume both follow a Normal distribution. What can be concluded at the the a = 0.05 level of significance level of significance? For this study, we should use Select an answer a. The null and alternative hypotheses would be: Ho: Select an answer Select an answer v Select an answer v (please enter a decimal) H1 : Select an answer Select an answer v Select an answer . (Please enter a decimal) b. The test statistic ? = (please show your answer to 3 decimal places.) c. The p-value = (Please show your answer to 4 decimal places.) d. The p-value is ? 7 a e. Based on this, we should Select an answer |the null hypothesis. f. Thus, the final conclusion is that ... The results are statistically insignificant at a = 0.05, so there is statistically significant evidence to conclude that the population mean time in the shower for the poor is equal to the population mean time in the shower for the rich. The results are statistically significant at a = 0.05, so there is sufficient evidence to conclude that the mean time in the shower for the thirteen poor people that were surveyed is more than the mean time in the shower for the thirteen rich people that were surveyed. The results are statistically insignificant at a = 0.05, so there is insufficient evidence to conclude that the population mean time in the shower for the poor is more than the population mean time in the shower for the rich. The results are statistically significant at a = 0.05, so there is sufficient evidence to conclude that the population mean time in the shower for the poor is more than the
