The Journal of Professional Issues in Engineering Education and Practice (Apr.2005) reported on the results of a 2005 survey of courses offered atundergraduate engineering programs. Of the 90 engineering programs thatparticipated in the 2005 survey, 78 covered fluid mechanics. In a survey taken 20years earlier (Engineering Education, Apr. 1986), 76 of the 100 undergraduateengineering programs covered fluid mechanics. Conduct a test to determinewhether the fraction of undergraduate engineering programs covering fluidmechanics increased from 1986 to 2005. Use significance level alpha= .01

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." Figure 2.

The Fish and Game Department stocked a lake with fish in the following proportions: 30% catfish, 15% bass, 40% bluegil, and 15% pike. Five years later it sampled the lake to see if the distribution of fish had changed. It found that the 500 fish in the sample were distributed as follows. Catfish Bass Bluegill Pike 89 122 218 71 A USE SALT In the 5-year interval, did the distribution of fish change at the 0.05 level? (a) What is the level of significance?

Weatherwise is a magazine published by the American Meteorological Society. One issue gives a rating system used to classify Nor'easter storms that frequently hit New England and can cause much damage near the ocean. A severe storm has an average peak wave height of ? = 16.4 feet for waves hitting the shore. Suppose that a Nor'easter is in progress at the severe storm class rating. Peak wave heights are usually measured from land (using binoculars) off fixed cement piers. Suppose that a reading of 35 waves showed an average wave height of x = 17.3 feet. Previous studies of severe storms indicate that ? = 3.5 feet. Does this information suggest that the storm is (perhaps temporarily) increasing above the severe rating? Use ? = 0.01. (a) What is the level of significance? State the null and alternate hypotheses. H0: ? = 16.4 ft; H1: ? ≠ 16.4 ft H0: ? > 16.4 ft; H1: ? = 16.4 ft H0: ? < 16.4 ft; H1: ? = 16.4 ft H0: ? = 16.4 ft; H1: ? > 16.4 ft H0: ? = 16.4 ft; H1: ? <…
Doctors are interested in the relationship between the dosage of a medicine and the time required for a patient's recovery. Table 2 shows, for a sample of 10 patients, dosage levels (in grams) and recovery times (in hours). These patients have similar characteristics except for medicine dosages.

Across the nation, many college students have been complaining to the dean of students about the temperature in the classrooms being at an "uncomfortable level", either too cold or too hot. Baylor's dean of students is interested in determining the true proportion of Baylor students that feel the classroom temperature is at an uncomfortable level. Out of a random sample of 200 Baylor students, ninety-eight say that the classrooms are either too hot or too cold. a. What is the parameter of interest? b. What is the point estimate you would calculate to estimate the parameter? What is its value?
In a study, the effects of the mane of a male lion as a signal of quality to mates and rivals was explored. Four life-sized dummies of male lions provided a tool for testing female response to the unfamiliar lions whose manes varied by length (long or short) and color (blonde or dark). The female lions were observed to see whether they approached each of the four life-sized dummies. Complete parts (a) through (e) below. a. Identify the experimental units. Choose the correct answer below. The female lions The male dummies The mane colors The mane lengths Part 2 b. Identify the response variable. Choose the correct answer below. A. Whether or not (yes or no) the mane length affected how the female lions reacted to a male dummy. B. Whether or not (yes or no) the female lions approached the same dummies. C.

The NTSB wants to estimate the difference between the average stopping distance for a car traveling 40 MPH on wet versus dry pavement. Ten vehicles were used for the study where each vehicle was driven at 40 MPH and came to a sudden stop on both wet pavement and dry pavement.
