We do not reject the Null Hypothesis
Step-by-step explanation:
From the question we are told that:
Sample size 
Population mean 
Sample mean 
Standard deviation 
Significance level 
Generally the Null and and alternative Hypothesis are as follows


Therefore t critical Value is


Where

Therefore
From t Table

Generally the equation for Z Critical is mathematically given by



Therefore
Since the t test statistics is greater than the Critical value
Hence,we do not reject the Null Hypothesis
