Question 1 2 pts Consider the following hypothesis test: Claim: o # 9.1 Sample Size: n = 8 Significance Level: a = 0.01 Enter the smallest critical value. (Round your answer to nearest thousandth.) Question 2 3 pts The table below shows the weights of seven subjects before and after following a particular diet for two months. Subject / A / B / C / D / E / F / G Before / 151 / 154 / 153 / 153 / 152 / 155 / 150 After / 154 / 152 / 153 / 152 / 152 / 151 / 154 Using a 0.05 level of significance, test the claim that the diet is not effective in reducing weight (after minus before is not negative). Use the p-value method of hypothesis testing. Enter the test statistic. (Round your answer to nearest hundredth.)Question 3 3 pts A random sample of 8 women resulted in systolic blood pressure levels with a mean of 137 and a standard deviation of 6.7. A random sample of 11 men resulted in systolic blood pressure levels with a mean of 143 and a standard deviation of 1.8. Use a 0.05 signicance level and the critical value method to test the claim that blood pressure levels for women vary more than blood pressure levels for men. Enter the smallest critical value. (Round your answer to nearest ten- thousandth.) Question 4 2 pts Assume that you want to test the claim that the paired sample data come from a population for which the mean difference is pd = 0. x / 2 3 4 6 3 y / 6 8 8 7 13 Compute the absolute value of the test statistic. (Round your answer to nearest hundredth. Hint: The correct test statistic is positive.)
