A medical researcher wants to determine if the average hospital stay of patients that undergo a certain procedure is greater than 9.1 days. The hypotheses for this scenario are as follows: Null Hypothesis: μ ≤ 9.1, Alternative Hypothesis: μ > 9.1. If the researcher takes a random sample of patients and calculates a p-value of 0.2003 based on the data, what is the appropriate conclusion? Conclude at the 5% level of significance. Question 5 options: 1) The true average hospital...
