d .
No proof was used in CLT . It still a hypothesis
6 . The post anaesthesia care area ( recovery room ) at St . Luke ’ s Hospital in Pflugerville , Ontario , was broadened . The move will mean that the mean number of people per day can also be enlarged . A random sampling was conducted in order to determine the patients coming after the broadening .

a What is the null hypothesis ? The mean number of patients per day arrived to be 25 or less .
b What is the alternative hypothesis ? The mean number of patients per day will be greater than 25
c What specific test will you use to test the hypotheses at α = 0.05 ? t-test
d What is the p-value for the test ? p = 0.0087
e Interpret the meaning of this p-value . The probability of arriving with the test statistics is 2.6935 if the null hypothesis holds to be true . This is the value used in t-statistic excluding the null hypothesis .

What is the critical value for the test ? ( Assume α = 0.05 .) |

g Interpret the meaning of this critical value . If we like to manipulate the type I error to become 0.05 or lesser , then the greatest value for the test should be1.7613 .
There must be more explanation here .
