The board of a major credit card company requires that the mean wait time for customers when they call customer service is at most 5.00 minutes. To make sure that the mean wait time is not exceeding the requirement, an assistant manager tracks the wait times of 51 randomly selected calls. The mean wait time was calculated to be 5.42 minutes. Assuming the population standard deviation is 1.95 minutes, is there sufficient evidence to say that the mean wait time for customers is longer than 5.00 minutes with a 90 % level of confidence? Step 1 of 3: State the null and alternative hypotheses for the test. Fill in the blank below. Answer Ho: μ = 5.00 Ha P 0 # 5.00 Keypad Keyboard Shortcu Tables

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:

Strength of concrete: The compressive strength, in kilopascals, was measured for concrete blocks from five different batches of concrete, both three and six days after pouring. The data are as follows. Can you conclude that the mean strength after three days is less than the mean strength after six days? Let u, represent the mean strength after three days and u, = 4, -Hh.
