Peter Thompson, in charge of office supplies at Top Hill Estates., would like to predict the quantity of paper used in the office photocopying machines per month. He believes that the number of clients seen in a month influences the volume of photocopying performed. He has compiled the following recent monthly data: (You are to use Excel for this problem) Number of clients in a Month Sheets of Photocopy Paper Used (1000's) 40 26 50 54 40 23 34 52 24 12 25 26 22 15 22 26 a. Develop the least squares estimated regression equation that relates sheets of photocopy paper used to the number of clients. b. Use the regression equation developed in part (a) to forecast the amount of paper used in a month when 36 clients are expected. c. Compute SSE, SST, and SSR.
The percentage of employees who cease their employment during a year is referred to as employee turnover, and it is a serious issue for businesses. The following table shows the cost, in millions of dollars, to a certain company for a given employee turnover percentage in a year.
Shelia’s doctor is concerned that she may suffer from gestational diabetes (high blood glucose levels during pregnancy). There is variation both in the actual glucose level and in the blood test that measures the level. A patient is classified as having gestational diabetes if her glucose level is above 136 milligrams per deciliter (mg/dl) one hour after ingesting a sugary drink. Shelia’s measured glucose level one hour after the sugary drink varies according to the Normal distribution with μ = 125 mg/dl and σ = 11 mg/dl. a)What are the mean and standard deviation of the distribution of sample proportion if measurements are made instead on 40 separate days? b)If measurements are made on 40 separate days and the mean result is compared with the criterion 140 mg/dl, what is the probability that Shelia is diagnosed as having gestational diabetes? c)Let’s consider what could happen if we took 40 separate measurements from Shelia. What is the blood glucose level L such that the probability…
