An online distributor of healthcare products maintains data on all transactions. The information that is recorded is shown in the sample transaction record below: Date of purchase 01/03/2010 Customer Name Customer Robert Jones 12943762 Zip Code Product 84321 6387450 Amount of Purchase 28.50 1. Which of the variables in the data table are numerical? (c) Amount of Purchase (a) Product Number (b) Customer Number (d) All of these variables are numerical. 2. At the end of each month, a new data table is generated that has a row for each day of the month, and columns labeled Date, Total Number of Transactions, and Total Amount Purchased. The production of this new data table is an example of (a) Re-coding the data (b) Aggregating the data (c) Use of a Likert Scale (d) Ordinal variables The operations manager of a bank has been monitoring the time required to assist customers who use the bank's drive-up facility. Over a one-month period, 525 eustomers using the facility were selected at random and the time to assist the customer was recorded. The histogram for the service times was nearly bell-shaped and symmetric. A summary of the data is given below: Summary Mean Standard deviation Lower quartile Median Upper quartile Time (minutes) 6.8 .85 62 6.9 7.5 3. Based on this data, the Empirical Rule indicates that 95% of all customer assistance times will be in which of the following intervals? (a) (5.1, 8.5] (b) [5.95, 7.65] (c) [43,9.5] (d) (4.2.9.4 (e) [5.2. 8.6] 4 Which of the following statements is accurate concerning the summarized service times: (a) 50% of the service times recorded are greater than 6.8 minutes. (b) The middle 50% of the service times are in the interval [5.95, 7.65]. (c) The smallest 25% of the service times recorded are less than 5.95 minutes. (d) The IQR for the service times is 1.7 minutes. (e) The largest 25% of the service times recorded are greater than 7.5 minutes 5. A boxplot is to be constructed for the service times that were recorded. Which of the following service times would be considered high outliers for the boxplot? (d) 9.6 minutes (a) 9.1 minutes (b) 9.2 minutes (c) 9.4 minutes (e) All of (a)-(d) would be outliers in the boxplot. (1) None of (a)-(d) would be outliers in the boxplot. The following data were collected from a survey of 10 randomly selected college students.
