    In two independent samples, from populations that are normally distributed , x1 = 35.0, s1 = 5.8, n1 = 12 and x2 = 42.5, s2 = 9.3, n2 = 14. Using the 0.05 level of significance, test Ho:u1 versus H1:u1 = u2.

    2. The product development team for a notebook computer company has shown picture A to a large sample of potential buyers and picture B to another, asking each perosn to indicate what they "would expect to pay" for such a product. The data resulting from the tow pictures are provided. Using the 0.05 level of significance, determine whether the prototypes migh not really differ in terms of the price that potential buyers would expect to pay. Identify and interpret the p-value for the test. Construct and interpret the 95% confidence interval for th difference between the population means. Is the hypothesized difference (0.00) within the interval? Given the presence or absence of the 0.00 value within the interval, is this consistent with the findings of the hypothesis test?
