: The postanesthesia care area (recovery room) at St. Luke's Hospital in Maumee, Ohio, was recently enlarged. The hope was that with the enlargement the mean number of patients per day would be more than 25. A random sample of 15 days revealed the following number of patients.
25 27 25 26 25 28 28 27 24 26 25 29 25 27 24
At the .01 significance level, can we conclude that the mean number of patient per day is more than 25? Estimate the p-value and interpret it. This question is from textbook

25. A random sample of 15 days revealed the following number of patients.
25 27 25 26 25 28 28 27 24 26 25 29 25 27 24
At the .01 significance level, can we conclude that the mean number of patient per day is more than 25? Estimate the p-value and interpret it.
-------------------------------------
Find the mean of the sample of 15 counts.
Ho: u = 25
Ha: u > 25
---
Run a T-test; it will tell you the test statistic and the p-value
The p-value is the probability the test statistic could have been
higher. If the p-value is greater than 1% do not reject Ho.
