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.

Explanation:
The contribution margin per patron is the ratio of the total contribution to the number of patrons. The total contribution is the difference between the total sales and the total variable cost.
Hence, the contribution per matron may also be derived as the difference between the sales per patron and the variable cost per patron.
The variable cost here is the cost of providing dinner per ticket as such,
Contribution margin per patron
= $40 - $22
= $18

Explanation:
According to Regulation Crowdfunding, an individual can invest 10% of their annual income across all crowdfunding offerings in a 12-month period.
Kim's annual income = $900,000
Kim's investing limit on crowdfunding offerings = $900,000
Since Kim haad already invested $25,000 in another offering, she can only invest $65,000 in Beta's crowdfunding (= $90,000 - $25,000).
