Your local Target store is interested to know how much money, on average, their customers spend each visit in the housewares department. They go back through their records and draw a sample of 450 people and calculate each customer's average spending on housewares. a) Identify the population, sample, parameter, statistic and variable for this example. (4 pts) b) Describe a situation in which you would calculate a parameter rather than a statistic (3pts). For the 1,000 samples, the following is a breakdown of how much each spent: Amount spent on housewares # of people Under $10 127 $10 - $19.99 84 $20-$29.99 166 $30 and over 73 c) Determine the PDF and CDF of the amount spent on housewares (6 pts). d) If I sample a random person in the store, what is the probability that they will spend less than $30 on housewares? (4pts) e) Customers get a $5 coupon when they spend at least $20 in housewares. Of the next 200 people that visit the store, how many coupons can they expect to give away? (4 pts)
