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.) |
cv = |
1.7613 |

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.
