Answer:
The test statistic t of the sample is -0.804.
There is sufficient evidence to ascertain that the average number of years of work experience of MBA applicants is less than 3 years.
Explanation:
Null hypothesis: The average number of years of work experience of MBA applicants is 3 years.
Alternate hypothesis: The average number of yet of work experience of MBA applicants is less than 3 years.
Test statistic (t) = (sample mean - population mean) ÷ sd/√n
sample mean = 2.57
population mean = 3
sd = 3.67
n = 47
t = (2.57 - 3) ÷ 3.67/√47 = -0.43 ÷ 0.535 = -0.804
Assuming a 5% significance level
degree of freedom = n - 1 = 47 - 1 = 46
The critical value corresponding to 46 degrees of freedom and 5% significance level is 2.013.
Conclusion:
Reject the null hypothesis because the test statistic -0.804 is less than the critical value 2.013.
The years of work experience of MBA applicants is less than 3.
