How do you find the z-score corresponding to a score of X = 100 for the distributions given below? How do you know what direction they are going?
a. mu = 80 and sigma = 10b. mu = 80 and sigma = 5c. mu = 105 and sigma = 10d. mu = 105 and sigma = 5
Above, mu represents Mean and sigma represents Standard Deviation.
The point estimate for the difference between the proportions is:
Verify that the fitted values have the same mean as the actual y-values, and that the residuals have mean zero and show that the variance of the fitted values plus the variance of the residuals adds up to the variance of y. Find the R-squared.
An investigator wants to design a study to estimate the difference in the proportions of men and women who develop early onset cardiovascular disease

Inverse probability based on normal distribution - The data set has a bell-shaped distribution. Between what two prices do 68% of the houses lie?
The dimension is supposed to be 224 mm and the variance is unknown for the manufacturing process. Is there evidence that the mean dimension is not 221 mm? Assume the population is normally distributed. Use a = 0.05 and the critical value value met..
