uppose Laura, a facilities manager at a health and wellness company, wants to estimate the difference in the average amount of time that men and women spend at the company's fitness centers each week. Laura randomly selects 13 adult male fitness center members from the membership database and then selects 13 adult female members from the database. Laura gathers data from the past month containing logged time at the fitness center for these members. She plans to use the data to estimate the difference in the time men and women spend per week at the fitness center. The sample statistics are summarized in the table. Population Populationdescription Population mean(unknown) Samplesize Sample mean(min) Sample standarddeviation (min) 1 male ?1 ?1=13 ?⎯⎯⎯1=132.5 ?1=45.3 2 female ?2 ?2=13 ?⎯⎯⎯2=108.7 ?2=31.1 df=21.256 The population standard deviations are unknown and unlikely to be equal, based on the sample data. Laura plans to use the two-sample ?-procedures to estimate the…
The FDA conducted a study to determine whether corn in a certain region contained unhealthy levels of pesticides. A biologist classified pesticide levels greater than 6.0 parts per million (ppm) as unhealthy. The pesticide levels of a random sample of 23 bushels in the region were measured and recorded. The data are shown in the stemplot below. Pesticide Levels 2 | 8 3 | 0 3 | 5 8 8 4 | 1 1 2 4 | 6 8 8 5 | 0 1 2 2 3 4 5 | 9 9 6 | 3 4 6 | 6 8 Key: 2 | 8 = 2.8 ppm What proportion of bushels of corn in the sample had pesticide levels that are classified by the biologist as unhealthy? The mean pesticide level of the 23 bushels of corn in the sample was 4.90 ppm and the standard deviation was 1.12 ppm.Construct and interpret a 95 percent confidence interval for the mean pesticide level of corn in the region

QDES.B A study was undertaken to see how accurate food labeling for calories on food that is considered "reduced calorie". The group measured the amount of calories for each item of food and then found the percent difference between measured and labeled food. The group also looked at food that was nationally advertised, regionally distributed, or locally prepared. The data is in the following table ("Calories datafile," 2013).
