The production of wine is a multi-billion-dollar worldwide
industry. In an attempt to develop a model of wine quality as
judged by wine experts, data was collected from red wine variants
from a particular type of foreign wine. A multiple linear
regression model was developed from a sample of 45 wines. The model
was used to predict wine quality, measured on a scale from 0
(very bad) to 10 (excellent) based on the alcohol content (%) and
the amount of...

11. (5 points) A sample of 50 lenses used in eyeglasses yields a sample mean thickness of 3.10 mm and a sample standard deviation of .34 mm. The desired true average thickness of such lenses is 3.20 mm. Does the data strongly suggest that the true average thickness of such lenses is something other than is desired? Test the hypotheses using α = 0.05. Show all work that includes: stating the hypotheses, computing the value of the TS, finding the...

The FloridaLakes dataset describes characteristic of water samples taken at random Florida lakes. Acidity (pH) is given for each lake. Pure water has a pH of 7, which is neutral. Solutions with a pH less than 7 are acidic while solutions with a pH greater than 7 are basic or alkaline. The researchers would like to know whether on average the solutions in Florida lakes are acidic. The following two problems are based on this dataset. Problem 2 This problem...

7.
The National Institute on Alcohol Abuse and Alcoholism defines
binge drinking as a pattern of drinking that brings blood alcohol
concentration (BAC) levels to 0.08g/dL. It is cited as the most
common and deadly pattern of alcohol abuse in the country, which
can cause many health problems such as alcohol poisoning, sudden
infant death syndrome, and chronic diseases, to name a few. In the
binge drinking fact sheet published by the Center for Disease
Control and Prevention, the amount...

Reserve Problems Chapter 13 Section 2 Problem 2 An article in the American Journal of Emergency Medicine compared the ability to detect acute traumatic aortic injury (ATAI) on cervical x-ray images. The data consisted of 13 cases of ATAI, 19 cases with negative aortography (NAO) and 18 cases with multiple trauma (MT) without aortography. Measurements of the cervical soft-tissue width at the third cervical vertebrae generated the following results. Averages were 9.9, 9.2 and 7.4 mm and standard deviations were...
