Please review Section 11.1. Are you an impulse shopper? A survey of 500 grocery shoppers indicated that 16% of males and 42% of females make an impulse purchase every time they shop. Assume that the survey consisted of 250 males and 250 females. Let group 1 be the males and let group 2 be the females. a = 0.05 H : 1 = 1 2 H : 1 # 1 2 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 ($) 850 875 1200 1500 900 325 1150 1500 2000 1900 750 925 1250 1800 1100 1350 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: bo = (Round to one decimal place as needed.) b1 = (Round to one decimal place as needed.)
