A medical researcher wants to determine if the average hospital stay of patients that undergo a certain procedure is greater than 8.2 days. The hypotheses for this scenario are as follows: Null Hypothesis: μ ≤ 8.2, Alternative Hypothesis: μ > 8.2. If the actual mean is 16.2 days and the null hypothesis is not rejected, did a type I, type II, or no error occur?
Question 17 options:
1)
We do not know the p-value, so we cannot determine if an error has occurred.
2)
Type I Error has occurred
3)
No error has occurred.
4)
Type II Error has occurred.
5)
We do not know the degrees of freedom, so we cannot determine if an error has occurred.
