Exercise 7.3 Two independent experiments are run in which two different types of paint are computed. Eighteen specimens are painted using type A, and drying time (in hours) is recorded each. The same is done with type B. The population standard deviations are both known to be 1.0. Assume that the mean drying time is equal for the two types of paint, find P(XA – X3 > 1.0), where Xa and Xg are average drying times for samples of size na = DR = 18.

Intensive care units (ICUS) generally treat the sickest patients in a hospital. ICUs are often the most expensive department in a hospital because of the specialized equipment and extensive training required to be an ICU doctor or nurse. Therefore, it is important to use ICUs as efficiently as possible in a hospital. According to a 2017 arge-scale study of elderly ICU patients, the average length of stay in the ICU is 3.4 days (Critical Care Medicine journal article). Assume that this length of stay in the ICU has an exponential distribution. Do not round intermediate calculations. What is the probability that the length of stay in the ICU is one day or less (to 4 decimals)? 2857 b. What is the probability that the length of stay in the ICU is between two and three days (to 4 decimals)? What is the probability that the length of stay in the ICU is more than five days (to 4 decimals)? Hide Feedback

Cellulon, a manufacturer of home insulation, wants to develop guidelines for builders and consumers on how the thickness of the insulation in the attic of a home and the outdoor temperature affect natural gas consumption. In the laboratory, it varied the insulation thickness and temperature. A few of the findings are: Monthly Natural Gas Consumption (cubic feet), Thickness of Insulation (inches), Outdoor Temperature (ºF), y x1 x2 30.3 4.0 42.0 24.8 12 40 31.7 8 49 On the basis of the sample results, the regression equation is: yˆy⁢^⁢ = 62.93 − 1.25x1 − 0.78x2 How much natural gas can homeowners expect to use per month if they install 4 inches of insulation and the outdoor temperature is 42 degrees F? (Round your answer to 2 decimal places.) What effect would installing 7 inches of insulation instead of 4 have on the monthly natural gas consumption (assuming the outdoor temperature remains at 42 degrees F)?
