When the test statistic is in the non-critical region, then the null hypothesis must not be rejected. [ Select ] - When the population standard deviation is known and the sample size is more than 30, Z- test is more appropriate to use for testing hypotheses than t- test. [ Select ] For a two-tailed test, the absolute value of the test statistic is being compared to the absolute value of the critical value to make a decision. [ Select ]

Fresh Donuts! A donut company says that their donuts remain fresh for over 2 days on average. A donut watchdog organization samples 15 donuts and finds that on average they remain fresh 2.1 days with a standard deviation of 0.8 days. Evaluate the company's claim using a hypothesis test. Use a 5% level of significance. Assume that donut freshness follows a normal distribution.
