The results of a survey asking poor and rich people how many minutes they spend in the shower are shown below. Poor 8 16 32 18 29 17 31 34 22 14 36 23 19 Rich: 30 15 35 29 41 43 24 29 52 51 44 18 Assume both follow a Normal distribution. What can be concluded at the the a = 0.01 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 Select an answer (please enter a decimal) H1: Select an answer Select an answer Select an answer (Please enter a decimal) b. The test statistic ?v = (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 ?v a e. Based on this, we should Select an answer the null hypothesis. f. Thus, the final conclusion is that ... The results are statistically significant at a - 0.01, so there is sufficient evidence to conclude that the population mean time in the shower for the poor is less than the population mean time in the shower for the rich. The results are statistically insignificant at o - 0.01, so there is statistically significant evidence to conclude that the population mean time in the shower for the poor is equal # 8 K W 5 6 8 9 O e t y u O P -h g h K C V b n m
