7 b) Suppose that X₁, X2,
X24 are a random sample from a Normal distribution
N(μ, o2), where both µ and o² are unknown. Using this sample, we wish to test Ho
0² = 10 against Ha: o² < 10 using the rejection region RR = {S²: S² < c}. Determine
the value of c that will make the test have power 0.9 when o² = 2.

A new filtering device is installed in a chemical unit. Before its installation, a random sample yielded the following information about the percentage of impurity: y1 = 13.2, S12 =171.1, and n1= 16 After installation, a random sample yielded: y2 = 10.1, S22 = 74.7, n2 = 20 a) Can you conclude that the two variances are equal? Use α = 0.05.b) Has the filtering device reduced the percentage of impurity significantly? Use α = 0.05.

For the population of healthy female adults, the mean of the distribution is 4.8. Suppose that a female patient has taken six laboratory blood tests over the past several months and that the RBC count data sent to the patient’s doctor are 4.2, 4.9, 4.5, 4.1, 4.4, 4.3 with a sample mean of (x̄= 4.4) and a sample standard distribution s =.28. Do the given data indicate that the mean RBC count for this patient is lower than 4.8?
