Alcohol use in the United States increased during the first year of the COVID pandemic, as did the
number of alcohol-induced deaths (such as alcoholic liver disease, accidental alcohol poisoning,
disorders due to acute intoxication).
Here is a figure from the CDC representing the "Rates of alcohol-induced deaths in the United
States in 2020, broken down by sex and age group."

Foot ulcers are common problem for people with diabetes. Higher skin
temperatures on the foot indicate an increased risk of ulcers. The article “An
Intelligent Insole for Diabetic Patients with the Loss of Protective Sensation"

measurements of temperatures, in °F, of both feet for 18 diabetic patients. The
results are presented in the Table Q1.

To test the new coating, the inventor randomly selects one of the two tires on each of 50 bicycles to be coated with the new spray. The bicycle is then driven for 100 miles and the amount of the depth of the tread left on the two bicycle tires is measured (in millimeters). It is desired to determine whether the new spray coating improves the wear of the bicycle tires.

- This is a multipart question 6.) Diesel Dave has modified his massive truck to combat global cooling, and to roll coal on his neighbor Environmentalist Ed. With each blast of diesel exhaust fumes, Diesel Dave releases sulfur dioxide in a giantblack cloud. Every morning as Diesel Dave is leaving home he rolls coal into Environmentalist Ed's yard. Not surprisingly, Environmentalist Ed is diligently collecting data on the air quality in his yard. Suppose Diesel Davereleases sulfur dioxide in a normally distributed manner with a mean of 2800 ppm and a standard deviation of 120 ppm. What is the probability that on a random morning he will release sulfur dioxide greater than 3000ppm? Suppose in order to sue Diesel Dave, Environmentalist Ed needs the daily average level of sulfur dioxide emissions to exceed 3000 ppm. However, he can choose to take his mean measurement over 2, 3, or 15 days. Which number of days would maximize Environmentalist Edís chances of suing Diesel Dave?

For each pipe, two segments received coating A, two received coating B, and the remaining two received coating C. The pipes were placed in a corrosive environment for a period of time; then the depth of the deepest pit (in mm) caused by corrosion was measured for each segment on each pipe. The effect of interest is the coating; the pipe is a blocking factor, and there were two replications on each pipe. The following sums of squares were calculated: sum of squares for blocks = 11.2, sum of squares for treatments = 4.8, sum of squares for interactions = 18.4, total sum of squares = 44.7. a) Construct an ANOVA table. You may give ranges for the P-values. b) Are the assumptions for a randomized complete block design satisfied? Explain. c) Does the ANOVA table provide evidence that mean pit depth differs among coatings? Explain.arrow_forward4. (Exam 1 Summer 2020) Use the preamble below to answer the questions that follow An experiment to gain a better understanding of the role of various substances in melting ice was run in 2004 by Edinson Cavani, a researcher, in a certain lab in Memphis, TN. For each observation, a 10 ml block of ice was placed into water containing a given concentration of sugar, or salt, or a sugar and salt mix. The melting time for the ice block was measured in seconds and then converted to minutes. The three factors of interest were shape of ice block (lozenge, cylinder, and cube), solute (sugar, salt, and equal mix of sugar and salt), and concentration (5%, 10% 15%, 20%).

Dr. Castillejo feels that maximum pulse rate during the run is a good predictor in explaining the oxygen consumption in the blood stream. He asserts that if pulse rate at the end of the run increased, then the oxygen consumption will also increase, hence his/her heart is functioning well. Based on the R commander output below, check if the data on oxygen consumption and maximum pulse rate (from 152bpm to 196 bpm) support Dr. Castillejo's assertion. Make sure to interpret all necessary estimates. Give the expected oxygen consumption if maximum pulse rate is 160 bpm. Also, provide a measure that reports the adequacy of the model.
