Chapter 1, Problem 11CE
Best Buy sells Fitbit wearable technology products that track a person’s activity. For example, the Fitbit technology collects daily information on a person’s number of steps so that a person can track calories consumed. The information can be synced with a cell phone and displayed with a Fitbit app. Assume you know the daily number of Fitbit Flex 2 units sold last month at the Best Buy store in Collegeville, Pennsylvania. Describe a situation where the number of units sold is considered a sample. Illustrate a second situation where the number of units sold is considered a population.

You own a clothing store in Tacoma, Washington. One of the items you sell are sweaters with the logo "Make Tacoma Stink Again" to support the campaign to reopen the paper mill. You have many one-day sales and keep track six times of the size of the discount (in dollars) and the number of sweaters sold. Your data for the six sales is:
Sale number 1 2 3 4 5 6
Discount (in dollars) 4 4 6 14 4 4
Swearers Sold 6 10 4 26 16 10
What is your best estimate of the standard deviation in the number of sweaters sold in all the sales?

- BMX racing is a sprint sport where races range from around 30 to 45 seconds depending on the length of the track. Given races are over in such a short time, the start - commonly referred to as gate starts due to everyone lining up on a gate, are critical to success in the sport. A coach with a particular interest in data analysis coaching an elite athlete records data at a local racetrack for the time it takes their athlete to reach the bottom of the starting hill. The coach has found that the hill times for their athlete follow a normal distribution with mean 2.3 seconds and standard deviation 0.02 seconds. (a) What hill time distinguishes the slowest 10% of hill times? (b) What is the probability that a randomly selected hill time is less than 2.27 seconds? (c) Let X be the number of hill times that are less than 2.27 seconds from 10 separate starts. Assuming the athlete is well rested between starts, what distribution might you consider X to follow.

- After graduation, you take a job with Specialty Toys, Inc, a company that sells a variety of innovative children’s toys. Management has learned the best time to introduce a new toy for the holiday season is in October when many families begin looking for holiday gifts. Specialty plans to introduce a new product called "Weather Teddy," a talking teddy bear with a built in barometer that predicts weather conditions. When a child presses the bear’s hand, it will respond with one of five possible weather predictions, ranging from "It looks to be a very nice day! Have Fun!" to "I think it may rain today. Don’t forget your umbrella." Product tests show its predictions are about as good as those of many local weather forecasters. Since you understand statistics, your boss comes to you for help in deciding how many Weather Teddy units to order for the holiday season. She tells you the following facts: Members of the management team suggest ordering quantities of 15,000, 18,000, or 24,000…arrow_forwardState whether the following statement is true or false, and explain why. If the statement is false, state the true change. A high school reports that its students' SAT scores were down by 6% in one year. The next year, however, the test scores rose by 14%. The high school principal announces, "Overall, test scores have improved by 8% over the past two years."arrow_forwardplease asaparrow_forward
