At a recent meeting, the manager of a national call center for a major Internet bank made the statement that the average past-due amount for customers who have been called previously about their bills is now no larger than $33:00. Other bank managers at the meeting suggested that this statement may be in error and that it might be worthwhile to conduct a test to see if there is statistical support for the call center manager's statement. The accompanying fable contains data for a random sample of 67 customers from the call center population Assuming that the population standard deviation for past due amounts is known to be $56:00, what should be concluded based on the sample data? Test using a = 0 05, Ff Click the icon to view the data table. Sitate the appropriate null and alternative hypotheses Choose the correct answer below OA. He H - 33.00 O B. Ho Hx 33.00 OC. He ja- 33,00 HA 18 2 33 00 HA 1= 33,00 HA H # 33.00 OD. Ho H> 33,00 OF. Ho 1x 33 00 NF. Ho H s 33.00 HA HIS 33 00 HA HIS 33 00 HA H> 33 00 Calculate the test statistic =(Round to two decimal places as needed.) i want the p value too State the conclusion. Choose the correct answer below O A. Reject the null hypothesis. There is sufficient evidence at significance level a = 0.01 that the mean past-due amount for customers who have been called is greater than $21,00 O B. Reject the null hypothesis. There is not sufficient evidence at significance level a = 0.01 that the mean past-due amount for customers who have been called is greater than $21:00. O C. Do not reject the null hypothesis, There is not sufficient evidence at significance level a = 0.01 that the mean past-due amount for customers who have been called is not equal to $21,00 O D, Do not reject the null hypothesis. There is sufficient evidence nice level a = 0.01 that the mean past-due amount for customers who have been called is greater than $21,00 I need a correct answer please
