je=2 DS The peak shopping time at home improvement store is between 8:00 AM-11:00 AM on Saturday mornings. Management at the home improvement store randomly selected 55 customers last Saturday morning-and decided to observe their shopping habits. They recorded the number of items that each of the customers purchased as well as the total time the customers spent in the store. Identify the types of variables recorded by the home improvement store. Select one: O a. number of items - continuous; total time - discrete O b. number of items - continuous; total time - continuous O c. number of items - discrete; total time - discrete o d. number of items - discrete; total time - continuous 9:05 AM
Which of the following choices most correctly pairs precision and accuracy with the statistical calculation performed to measure it? Precision and accuracy are both measured with percent error. Precision and accuracy can only be found by graphing the data and finding R2. Precision is measured with percent error. Accuracy is measured with RSD. Precision and accuracy are both measured with RSD. Precision is measured with RSD. Accuracy is measured with percent error .

Prices of diamonds are determined by what is known as the 4 Cs: cut, clarity, color, and carat weight. The prices of diamonds go up as the carat weight increases, but the increase is not smooth. For example, the difference between the size of a 0.99-carat diamond and a 1-carat diamond is undetectable to the naked human eye, but the price of a 1-carat diamond tends to be much higher than the price of a 0.99 diamond. In this question, we use two random samples of diamonds, 0.99 carats and 1 carat, each sample of size 23, and compare the average prices of the diamonds. In order to be able to compare equivalent units, we first divide the price for each diamond by 100 times its weight in carats. That is, for a 0.99-carat diamond, we divide the price by 99. For a 1 carat diamond, we divide the price by 100. The distributions and some sample statistics are shown below I have attached the questions and the chart in the images section. Thank you
