Question 4 (1 point)
The table below consists of 20 observations (age for each student in a given KSU class). Note that this class is just one sample and we really don't know much about the actual distribution of student age at KSU. Given this information, please conduct a hypothesis test for the average age of all KSU students being at 22. Please do so with a 90% confidence level. (HINT: you may wish to start by obtaining descriptive statistics in Excel, so copy and paste the table below into Excel).
Question 4 options:
We can't reject the null hypothesis that the average age of KSU students is 22
We reject the null hypothesis that the average age of KSU students is 22
None of the above as there is not enough information provided to conduct such a test
