“The ABC Co. is considering a new consumer product. They believe there is a probability of 0.4 that XYZ Co. will come out with a competitive product. If ABC adds an assembly line for the product and XYZ does not folow with a competitive product, their expected profit is $40,000; if they add an assembly line and XYZ does follow, they still expect a $10,0000 profit. If ABC adds a new plant addition and XYZ does not produce a competitive product, they expect a profit of $600,000; if XYZ does compete for this market, ABC expects a loss of $100,000.multiple […]

An integer n is even if n = 2k for some integer k. An integer n is odd if n = 2k+1 for some integer k. There are no integers that are both even and odd! Examples: 6 is even since 6 = (2)(3), −8 is even since −8 = (2)(−4), 0 is even since 0 = (2)(0), 3 is odd since 3 = 2(1) + 1, and −9 is odd since −9 = (2)(−5) + 1.

A bank tests the null hypothesis that the mean age of the bank’s mortgage holders is less than or equal to 45 years, versus an alternative that the mean age is greater than 45 years. They take a sample and calculate a p-value of 0.0202. The null hypothesis would be rejected at a significance level of α= 0.05. Please answer with calculation and explanation

Because different sales trainees are assigned to the two experimental groups, it is reasonable to believe that the two samples are independent. Assuming that the normality assumption holds, and using the equal variances procedure, test the hypotheses you set up in part a at level of significance .10, .05, .01 and .001. How much evidence is there that type A training produces results that are superior to those of type B? (Round your answer to 3 decimal places.)
