Question 1 (3 points) In an upper tail hypothesis test for a population mean when the population standard deviation is known, at the 0.123 level of significance, the critical value 2 = __________ . Question 2 (3 points) J Saved In a two-tailed hypothesis test for a population mean when the population standard deviation is known, if the test statistic is determined to be 2 = -2.5, the p-value for this test is 0 0.2112 @ 0.0124 Q 0.0062 0 0.1056 Question 3 (3 points) Saved The manager of a department store has taken a random sample of 100 customers. The average length of time it took the customers in the sample to check out was 3.1 minutes with a standard deviation of 0.5 minutes. A hypothesis test is conducted to determine whether the mean waiting time of all customers is significantly more than 3 minutes. The p-value for this test is __________ . 0 between 0.05 and 0.10 6) between 0.01 and 0.025 0 between 0.025 and 0.05 O between 0.005 and 0.01 Question 4 (3 points) The null hypothesis should be rejected if the p-value is __________ the level of significance. 0 equal to O greater than or equal to 0 less than or equal to O greater than Question 5 (3 points) J Saved Hypothesis testing is used to determine whether a statement about the value of a __________ should or should not be rejected. 0 population statistic population parameter 0 sample statistic O sample parameter
