Step-by-step explanation:
Let
be the population mean .
Then, Null hypothesis : 
Alternative hypothesis : 
We assume that this is a normal distribution.
Given : Sample size : n=25 , since the sample is small (n<30) so we cannot apply z-test . Thus the test is t-test.
Sample mean : 
Population standard deviation : 
The test statistic for population mean is given by :-

i.e. 
Hence, the observed critical value = 2.5
