The Occupational Safety and Health Administration (OSHA) mandates certain regulations that have to be adopted by corporations. Prior to the implementation of the OSHA program, a company found that for a sample of 40 randomly selected months, the mean employee time lost due to job-related accidents was 45 hours. After implementation of the OSHA program, for a random sample of 45 months, the mean employee time lost due to job-related accidents was 39 hours. It can be assumed that the variability of time lost due to accidents is about the same before and after implementation of the OSHA program (with a standard deviation being 3.5 hours). Find a 90% confidence interval for the difference in the mean time lost due to accidents. Test the hypothesis that implementation of the OSHA program has reduced the mean employee lost time. Use a level of significance of 0.10.
According to a report published by the Center for Disease Control (CDC) in 2011, approximately one in two people with asthma had an asthma attack in 2008. A recent health survey conducted in 2015 by the National Health Center for Health Statistics collected asthma data for a U.S. adult sample. The survey data contains information on whether or not U.S adults with asthma living in the South had an asthma attack in the past 12 months. Using the given data, run a binomial test with a significance level of ?=0.05 to determine if the proportion of U.S. adults with asthma living in the South that have had an asthma attack in the past 12 months differs from 0.5. Use software to compute the ?-value for the binomial test. The hypothesis statements are H0:The relative frequency of people in the population who have had an asthma attack in the past year is 0.5.HA:The relative frequency of people in the population who have had an asthma attack in the past year is not 0.5.

A sample of 15 maple trees in Vermont were treated with one of three amounts of fertilizer, Low (group 1), Medium (group 2) and High (group 3). The volume in sap (measured in mL) produced by each tree was recorded, and a Single-Factor ANOVA test was performed, which ended up rejecting . The Summary table and the ANOVA table produced by Excel are given below: SUMMARY Groups Count Sum Average Variance Low 5 398.1 79.62 27.572 Medium 5 477.2 95.44 3.703 High 5 445.1 89.02 11.357 ANOVA Source of Variation SS df MS F Between Groups 633.0813333 2 316.5406667 22.27486395 Within Groups 170.528 12 14.21066667 Total 803.6093333 14 If you follow up the ANOVA test with a FORMAL Fisher's LSD Pairwise Comparison (PWC) test on , then use the information provided in the Excel-generated output to calculate the value of the Test Statistic (TS) that you would use to perform this PWC test.
