A newspaper published an article about a study in which researchers subjected laboratory gloves to stress. Among 228 vinyl gloves, 69% leaked viruses. Among228 latex gloves, 9% leaked viruses. Using the accompanying display of the technology results, and using a 0.10 significance level, test the claim that vinyl gloveshave a greater virus leak rate than latex gloves.

A computer manufacturer believes that the proportion of hardware malfunctions is different in humid climates than in dry climates. To test this claim, the manufacturer takes a random sample of 400 machines sold in Florida (humid) and 400 machines sold in Arizona (dry). The manufacturer finds that 44 of the machines in Florida and 24 of the machines in Arizona had hardware malfunctions. d. Does the evidence support the computer manufacturer's claim at the 10% significance level?
A grassroots group opposed to a proposed increase in the gas tax claimed that the increase would hurt working-class people the most, since they commute the farthest to work. Suppose that the group randomly surveyed 24 individuals and asked them their daily one-way commuting mileage. The results are in Table below. Using a 5% significance level, test the hypothesis that the three mean commuting mileages are the same. working-class professional (middle incomes) professional (wealthy) 17.8 16.5 8.5 26.7 17.4 6.3 49.4 22.0 4.6 9.4 7.4 12.6 65.4 9.4 11.0 47.1 2.1 28.6 19.5 6.4 15.4 51.2 13.9 9.3
A drug company is interested in investigating whether the color of their packaging has any impact on sales. To test this, they used five different colors (blue, green, orange, red, and yellow) for their packages of an over-the-counter pain reliever, instead of the traditional white package. The following table shows the number of packages of each color sold during the first month. Package color Blue Green Orange Red Yellow Number of packages sold 310 292 280 216 296 Using a 1% significance level, test the null hypothesis that the number of packages sold of each of these five colors is the same. Make sure to state the null and alternative hypotheses.

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.
