Answer: Option A.  ANOVA: Single factor

ANOVA or Analysis of Variance is a statistical technique that is used to determine if the difference between the means of three or more independent groups of data are statistically significant.  

ANOVA was developed in order to cater to the necessity of having a statistical technique to compare the difference between the means of three or more groups of data.

In this question the Dean wants to test the null hypothesis that the mean GPA is the same for Marketing, Management, Accounting and Finance majors. Since he needs to compare four independent groups of data, single factor ANOVA is the most appropriate Excel tool.

Liam borrowed a total of $35,000 to pay for college. he pays his parents 3% interest on the $8,000 he borrowed from them and pay
Lana71 [14]

Answer: Liam pays an average interest of 5.9% on the total $35,000.

Since the amounts borrowed and the respective interest rates are different, <u>the weighted average </u>will give us a better picture of the average interest paid on the loan.

We calculate weights based on the total amount borrowed.

                             Borrowing ($)                  Weights

Parents                     3000            \frac{3000}{35000} = 0.228571429

<u>Bank                       32000           \frac{32000}{35000} = 0.771428571 </u>

Total                       35000                                                                     1

Once we have the weights, we multiply the interest rates with the respective weights. Then we find the total of the (weights * Interest rate) column to find the weighted average or the average rate Liam pays.

                      Weights       Int Rates        Weights * Interest rates

Parents       0.228571429      0.03  0.228571429*0.03 = 0.006857143

<u>Bank           0.771428571       0.0680.771428571 *0.068 = 0.006857143</u>

Total                       1                                          0.059314286

Reika [66]

C) Increase interest rates in order to decrease the money supply

During high inflation, the Federal Reserve will increase rates so that it is harder to borrow money and people will not spend as much of what they already have. The goal of this is to slow down economic growth (which is tied to inflation) in the short term.
