A random sample of n = 4 scores is obtained from a normally distributed population with μ = 20 and σ = 4. What is the probability of obtaining a mean greater than 22 (i.e., p (M >22) for this sample?
Where you live, you can pick up an order from Costco in about 15 minutes by walking. We would like to test whether the average time for a robot delivery differs from this 15 minutes. Assuming the time X for a robot delivery is distributed as X-N (μ, o2), and we take a random sample of n=8, we wish to test Ho : μ = 15 US H₁: μ 15 at the 5% significance level. We observe n=8, = 23.1 and s=14.328 where s is the sample standard deviation. The value of the test statistic and the decision are 1.599, do not reject the null hypothesis 2.36, reject the null hypothesis 0.565, do not reject the null hypothesis 5.523, reject the null hypothesis
1. A study compared the number of tree species in unlogged forest plots to similar plots logged 8 years earlier. Independent random samples of both logged and unlogged plots were analyzed and the number of tree species was recorded. Tables 1 and 2 present the Shapiro-Wilk normality test for both types of forest plots and the Independent Samples t-test results.

A random sample is drawn from a normally distributed population with mean μ = 18 and standard deviation σ = 2.3; Are the sampling distribution of the sample mean with n = 26 and n = 52 normally distributed? Also calculate the probabilities that the sample mean is less than 18.6 for both sample sizes.
5. A quality control engineer found that the inner and outer diameters of their ball bearings, denoted respectively as X and Y, are random variables with E(X|Y = y) = 0.7 – 0.3y inches and Var(X|Y = y) = 0.0004y for all values of y. From his past experience he also knew that the mean and variance of the outer diameters were E(Y) = 0.7 inches, and Var(Y) squared inches. = 0.0001 %3D • (i) What are the conditional random variables, E(X|Y) and Var(X|Y)? • (ii) Find the mean of the inner diameters, E(X). • (ii) Find the variance of the inner diameters, Var(X).
