A medical researcher wants to determine if the average hospital stay of patients

Question

A medical researcher wants to determine if the average hospital stay of patients that undergo a certain procedure is greater than 7.6 days. The hypotheses for this scenario are as follows: Null Hypothesis: 7.6, Alternative Hypothesis: > 7.6. If the researcher takes a random sample of patients and calculates a p-value of 0.8746 based on the data, what is the appropriate conclusion? Conclude at the 5% level of significance. Question 7 options: 1) We did not find enough evidence to say the true average hospital stay of patients is longer than 7.6 days. 2) We did not find enough evidence to say the true average hospital stay of patients is shorter than 7.6 days. 3) The true average hospital stay of patients is significantly longer than 7.6 days. 4) We did not find enough evidence to say a significant difference exists between the true average hospital stay of patients and 7.6 days. 5) The true average hospital stay of patients is shorter than or equal to 7.6 days.

Explanation / Answer

The null hypothesis is not rejected at alpha=0.05, therefore, there is not sufficient sample evidence to ocnclude that the true avergae hospital stay of patients is longer than 7.6 days. Option 1)
