I need a help!

Suppose University claimed that the average wait time to receive the results of their Covid test Wis 11 hours. A student reporter thought that was too low so to test the claim he took a random Simple of 10 students and found their average wait time was 13 hours with a SD = 4 hours. (Assume the wait times of the thousands of students who take the test roughly follows the normal curve.) The null hypothesis is Ho: 5: = 11 and the alternative is HA: |.| > 11. a. which of the following best describes the null box? 0 it has thousands of tickets with an average = 11 and an unknown SD. 0 it has thousands of tickets with an average = 13 and SD = 4 C it has 10 tickets with an average = 11 and SD = 4 0 it his thousands of tickets. On each ticket is written a wait time. The eXict peroentiges are unknown and estimited from the sample. Submit Answer Tries 0/99 I). which test statistic is most approprlate to use? 0 z 0 t O neither Submit Answer Tries 0/99 1:. You oomputed both the SE"avg and the 5Eavg but you forgot which is which. The two numbers are 1.33 and 1.26, which is the SE+avg? O 1.33 O 1.26 G not enough Info Submit Answer Tries 0/99 I]. Suppose you decided to do a ttest.
