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.

What is Labor force?
The labor force is made up of both employed people and unemployed people, and the unemployment rate is calculated by dividing the number of jobless people by the total labor force. If a person works for compensation or runs their own business for at least an hour any day of the week, including the twelfth of the month, they are regarded to be employed. If a person works for compensation or runs their own business for at least an hour any day of the week, including the twelfth of the month, they are regarded to be employed. In a family-run firm, individuals who put in at least fifteen hours of unpaid work are also regarded as employees. Employed people include those who are temporarily away from their work due to a vacation, illness, inclement weather, or other personal reasons. Those who worked full-time (35 hours or more during the survey week) and those who worked part-time are both considered to be in the employed category.
