A researcher is trying to determine if promotions are based on gender.
The researcher studies two companies and records the gender of the
employees that received pay grade promotions during the last year.
The results are shown in the following table:
....................Female employees promoted..Male employees promoted
Endothon Company....511/825 = 62%..............89/108 = 82%
Quality Apple Farms.137/417 = 33%..............131/375 = 35%
Total...............648/1242 = 52%.............220/483 = 46%

A) Yes, because while each of the companies promoted a higher
percentage of male employees, overall a higher percentage of women

C) No, because a higher percentage of female employees were
promoted by each company

{{ Scatterplot trending right and up }}
The regression equation y = 3.1 x + 16.2 estimates the amount spent (in
dollars) based on the amount of time spent in a grocery store (in
minutes).
Using the regression equation, what is the amount of money predicted
to be spent when a customer spends 15 minutes in the grocery store?
