Explanation:
Performance of the student's t-test as
n<30
Calculating the Null hypothesis:
Calculating the Alternative Hypothesis:
Calculating the level of significance
Calculating the test statistic:
Because of the population standard deviation, perform z test
Decision:
Comparison of p-value test statistics and decision-making.
Hypothesis P<0.05 Reject.
P>0.05 No hypothesis rejecting zero.
P-Value = 0.907653.
At p<0.05 the result is not significant.
Null hypothesis not to be rejected.
Accepting the null hypothesis.
