Use the @ = 0.10 level of significance and the P-value method with the TI-84 Plus calculator What do you conclude? Part 1 of 4 (=) State the null and alternate hypotheses. Ho: Number of children and number of siblings are independent. A: Number of children and number of siblings are not independent. Part : 1 / 4 Part 2 of 4 (b) Find the P-value. Round your answer to at least four decimal places. The P-value isNo smoking: The General Social Survey conducted a poll of 08) adults in which the subjects were asked whether they agree that the government should prohibit smoking in public places. In addition, each was asked how many people lived in his or her household. The results are summarized in the following contingency table.

Ho: Household size and opinion are independent. H: Household size and opinion are not v independent. Part: 1 / 4 Part 2 of 4 (b) Find the P-value. Round your answer to at least four decimal places. The P-value isA recent study examined the effects of carbon monoxide exposure on a group of construction workers. The following table presents the numbers of workers who reported various symptoms, along with the shift (morning, evening, or night) that they worked.

Use the @ = 0.03 level of significance and the F-value method with the TI-84 Plus calculator. What do you conclude? Part 1 of 4 State the null and alternate hypotheses. H: The shift and reported symptoms are independent. A: The shift and reported symptoms are not independent. This hypothesis test is a right-tailed test. Part: 1 / 4 Part 2 of 4 Find the P-value. Round your answer to four decimal places. The F-value is
