The advertised claim for batteries for cell phones is set at 48 operating hours with proper charging procedures. A study of 5000 batteries is carried out and 15 stop operating prior to 48 hours. Do these experimental results support the claim that less than 0.2 percent of the company’s batteries will fail during the advertised time period, with proper charging procedures? Use a hypothesis-testing procedure with α = 0.01.

A random sample of 100 male employees showed that 42 are working from home while a random sample of 100 female employees showed that 63 are working from home. Are the two population proportions equal? Test at alpha=0.05. What is Ho and Ha? And what is the test statistic value for this test? Based on the test statistic value, what is your decision?
In early November 2019, Gallup conducted a national poll of 1015 U.S. adults that asked which country is the leading economic power in the world. Of those sampled, 538 said China. At the 0.01 level of significance, does the data provide sufficient evidence to conclude that, at the time, a majority (more than 50%) of U.S. adults consider China the leading economic power in the world? Solve using the p-value approach. Define the parameter we are testing and setup a hypothesis test to see if a majority of U.S. adults consider China the leading economic power in the world. Calculate the test statistics for this hypothesis test. What is the p-value for this hypothesis test?
You predict that a salesclerk at the mall will take longer to help a potential customer that is dressed in sloppy clothes vs a potential customer dressed in business attire. After running the study you find support for your hypothesis with the obtained value exceeding the critical value at the p < .05 level. Why wouldn't you want to say that you proved your hypothesis correct? What other sources might be a better explanation for your findings?

What is the appropriate conclusion for this test? (Do not reject OR reject) H₀ and conclude that there (is or is not) sufficient evidence that mice with an average life span of 32 months will live to be (less or greater) than 42 months old when 40% of the calories in their diet are replaced by vitamins and protein.

Delta has a new jumbo jet they believe will decrease the flight time from Newark to London Heathrow. To be faster than its competitors, the mean must be less than 6 h 50 minutes (or 410 minutes). Because of costs, the agency monitoring the flight times only requires that eight trials be run. The results (in minutes) are given in the spreadsheet. If the FAA requires that the agency be 90% confident of its findings (so an alpha level of 0.10), what should the agency report? Conduct an appropriate hypothesis test using Excel. Assume the population distribution is approximately normal.
What is null and alternative hypothesis for this case? The U.S. Department of Health monitors fishing waters, to determine if the bacteria count has risen above a maximum safe level of 70.
An inventor, working at a science tech lab, believes innovations in satellites are increasing. The inventor would like to test the claim that the average number of new ideas for satellite development per month at the science tech lab is over 60 new ideas. Using the computed test statistic of 1.05 and the critical value of 1.28, is there enough evidence for the inventor to reject the null hypothesis? Use the graph below to interpret the critical value. First select the appropriate test type (left-, right-, or two- tailed), then plot the points along the x-axis (for the critical value and test statistic), and use them to choose the appropriate interpretation.
It is believed that a sweetener called xylitol helps prevent ear infections. In a randomized experiment, 165 children took a placebo and 68 of them got ear infections. Another sample of 159 children took xylitol and 46 of them got ear infections. The scientists believe that the proportion of ear infections in the placebo group will be greater than the xylitol group. Test this hypothesis at α = 0.025.
