Acomputer manufacturer estimates that its cheapest screens will last less than 2.8 years. a random sample of 61 of these screens has a mean life of 2.7 years. the population is normally distributed with a population standard deviation of 0.88 years. at α=0.02, what type of test is this and can you support the organization’s claim using the test statistic(a) claim is null, fail to reject the null and cannot support claim as test statistic (-0.89) is not in the rejection region defined by the critical value (-2.33)(b) claim is alternative, reject the null and support claim as test statistic (-0.89) is not in the rejection region defined by the critical value (-2.33)(c) claim is null, reject the null and support claim as test statistic (-0.89) is not in the rejection region defined by the critical value (-2.05)(d) claim is alternative, fail to reject the null and cannot support claim as test statistic (-0.89) is not in the rejection region defined by the critical value (-2.05)
