Hurricane Andrew swept through southern Florida causing billions of dollars of damage. Because of the severity of the storm and the type of residential construction used in this semitropical area, there was some concern that the average claim size would be greater than the historical average hurricane claim of $24,000. Several insurance companies collaborated in a data gathering experiment. They randomly selected 24 homes and sent adjusters to settle the claims. In the sample of 24 homes, the average claim was $25,500 with a population standard deviation of $5100. Is there sufficient evidence at a 0.05 significance level to support the claim that the home damage is greater than the historical average? Assume the population insurance claims is approximately normally distributed. Step 1 of 3: State the null and alternative hypotheses for the test. Fill in the blank below.

The average final exam score for the statistics course is 78%. A professor wants to see if the average final exam score for students who are given colored pens on the first day of class is higher. The final exam scores for the 13 randomly selected students who were given the colored pens are shown below. Assume that the distribution of the population is normal. 90, 84, 93, 77, 95, 79, 82, 70, 85, 70, 83, 100, 90 What can be concluded at the the a = 0.05 level of significance level of significance?
A researcher conducts a hypothesis test on a population proportion. Her null and alternative hypothesis are H0:p = 0.4 and Ha: p < 0.4. The test statistic and p-value for the test are z = -3.01 and p-value = 0.0013. For asignificance level of a= 0.05, choose the correct conclusion regarding the null hypothesis.H0:________________________ Ha:_______________________Compare the p-value and a:_______________Decision:_________________________Conclusion:___________________________________________________________
9B: A publisher reports that 36% of their readers own a laptop. A marketing executive wants to test the claim that the percentage is actually less than the reported percentage. A random sample of 320 found that 30% of the readers owned a laptop. Is there sufficient evidence at the 0.01 level to support the executive's claim? Step 5: Identify the value of the level of significance. Step 6: Make the decision to reject or fail to reject the null hypothesis. Step 7:
