A medical researcher wants to determine if the average hospital stay of patients that undergo a certain procedure is less than 5.3 days. The hypotheses for this scenario are as follows: Null Hypothesis: µ 2 5.3, Alternative Hypothesis: µ < 5.3. If the researcher takes a random sample of patients and calculates a p-value of 0.0922 based on the data, what is the appropriate conclusion? Conclude at the 5% level of significance. 1) The true average hospital stay of patients is longer than or equal to 5.3 days. 2) We did not find enough evidence to say a significant difference exists between the true average hospital stay of patients and 5.3 days. 3) The true average hospital stay of patients is significantly shorter than 5.3 days. 4) We did not find enough evidence to say the true average hospital stay of patients is longer than 5.3 days. O 5) We did not find enough evidence to say the true average hospital stay of 5) patients is shorter than 5.3 days.
