Discuss the below:
Q: Consider a sample x1, x2, ..., xn and suppose that the values of x, s2, and s have been calculated.
a. Let yi = xi‾ for i = 1, ..., n. How do the values of s2 and s for the yi's compare to the corresponding values for the xi's? Explain.
b. Let zi = (xi - x‾ ) / s for i = 1, ..., n. What are the values of the sample variance and sample standard deviation for the zi's?
