8.2(#4)Find pvalue(round 4dec places)(Underline it)Say whether you Reject null hypothesis or not ? **Daily Driving** The average number of miles a person drives per day is 24. A researcher wishes to see if people over age 60 drive less than 24 miles per day. She selects a random sample of 28 drivers over the age of 60 and finds that the mean number of miles driven is 23.2. The population standard deviation is 3.4 miles. At α = 0.10, is there sufficient evidence that those drivers over 60 years old drive less than 24 miles per day on average? Assume that the variable is normally distributed. Use the P-value method with a graphing calculator.**Part 1 of 4**(a) State the hypotheses and identify the claim.- \( H_0: \mu = 24 \) (not claim)- \( H_1: \mu < 24 \) (claim)This hypothesis test is a one-tailed test.P-value = ___

Previously, 3% of mothers smoked more than 21 cigarettes during their pregnancy. An obstetrician believes that the percentage of mothers who smoke 21 cigarettes or more is less than 3% today. She randomly selects 145 pregnant mothers and finds that 3 of them smoked 21 or more cigarettes during pregnancy. Test the researcher's statement at the a = 0.1 level of significance.

A decade-old study found that the proportion of high school seniors who felt that getting rich" was an important personal goal was 66%. Suppose that we have reason to believe that this proportion has changed, and we wish to carry out a hypothesis test to see if our belief can be supported. State the null hypothesis H. and the alternative hypothesis H, that we would use for this test. Ho: H OSO Submit Assignmen Privacy Accessibili Continue O 2021 McGraw-Hill Education.
