Suppose that 10 grades are drawn from a normal population whose standard deviation is 15.The observations are:
90 54 78 66 48 72 66 42 60 50
At 99% confidence,you want to determine whether the mean of the population from which this sample was taken is greater than 60.
a.State the null and alternative hypotheses.
b.Compute the value of the test statistic.
c.Compute the p-value.
d.Interpret the results.

a. H0: μ = 60 vs.H1: μ > 60
b. z =0.548
c. 0.2918
d. Cannot reject H0.Not enough evidence to say the mean is other than 60.

{Dishwasher Designs Narrative} Calculate the expected monetary value for each design with present information.Which design should be selected in order to maximize the firm's expected profit?
On May 02, 2024
EMV (a1)= (0.1)(30)+ (0.6)(19)+ (0.3)(11)= $17.7 million.
EMV (a2)= (0.1)(20)+ (0.6)(21)+ (0.3)(23)= $21.5 million.
EMV (a3)= (0.1)(10)+ (0.6)(15)+ (0.3)(45)= $23.5 million.
Since the most favorable expected monetary value occurs for design a3 (thus,EMV* = $23.5 million),design a3 would be the best alternative under the EMV criterion.
