![Problem #5: Students with the last name of U-Z:
Please review Section 11.1. Are you an impulse shopper? A survey of 800 grocery shoppers indicated that 36% of males and 42% of
females make an impulse purchase every time they shop. Assume that the survey consisted of 400 males and 400 females. Let group 1 be
the males and let group 2 be the females.
a = 0.01
2a = ת : ,H
Calculate the test statistic:
(Round to three decimal places as needed.)
Determine the critical value:
(Round to three decimal places as needed.)
State the Conclusion:
Please review Section 12.2. An agent for a residential real estate company in a suburb located outside a major city has the business objective
of developing more accurate estimates of the monthly rental cost for apartments. Toward the goal, the agent would like to use the size of an
apartment, as defined by square footage to predict the monthly rental cost. The agent selects a sample of 8 one-bedroom apartments and
the data are shown.
Size (Square Feet) Monthly Rent ($)

850
1350
1550

1600
1800
1900
925
1800
700
1300
1050
1300
Construct a scatterplot. Size is the x value and Monthly Rent is the y value. You can hand-draw, or use technology...label appropriately.
Use the least-squares method to determine the regression coefficients. If you use technology, include the documents or screen shots:
