Company Game Pro wants to know the lifetimes of two brands of handheld video games. The company's research and development departments, selects a sample of 10 video games of each brand for further analysis. The lifetime (in months) for each brand is tabulated as below. Brand B 29 39 38 43 45 49 53 38 44 43 The research assistant hypothesized that the median lifetime for video games with brand B is less than 40 months. Can you support the claim at $\alpha = 0.05$ using Sign test? List the signs for the lifetimes data of Brand B. * Your answer 1 point Compute the test statistic. * 1 point Your answer Obtain the critical value. * 1 point Your answer

Step 1
The hypothesized median is 40 months. We compare each data point to the hypothesized median and assign a "+" if the data point is greater than 40 and a "-" if the data point is less than 40. If a data point is equal to 40, we ignore it. Step 2: Let's compare Show more…

A manufacturer claims that the mean lifetime of its lithium batteries is 1,400 hours. A homeowner selects 25 of these batteries and finds the mean lifetime to be 1,380 hours with a standard deviation of 80 hours. Test the manufacturer's claim. Use a=0.05. Round the test statistic to the nearest thousandth. Write the Null and Alternative Hypotheses, draw the normal curve and label, show your results with the Classical and P-Value methods and write your conclusion.

A manufacturer claims that the average life of batteries used in their electronic games is 150 hours. The standard deviation is 20 hours. A consumer wishes to test the manufacturer's claim and accordingly tests 100 electronic games using this battery and found out that the mean life is equal to 169 hours. Using alpha at 0.05. a)What statistic is most applicable? b) The alternative hypothesis in is ? c) The computed statistic is? d)The decision is?

A manufacturer of running shoes knows that the average lifetime for a particular model of shoes is 15 months. A designer came with a new model of shoes which were worn by 15 individuals, and the lifetime of each of those pairs of shoes are given below: 15, 18, 17, 20, 16, 16.5, 15.5, 17.5, 19, 14, 21, 18.5, 16.5, 15, 14 a) State the appropriate hypotheses to test whether the lifetime of shoes are showing evidence of a longer lasting product than expected. b) Determine the mean and standard deviation for the lifetimes of the sample of shoes. c) Test the hypotheses stated in part (a) at a 5% level of significance, and comment on your findings.
