Using the z(a) notation (identify the value of a used within the parentheses), name each of the standard normal variable z’s shown in the following diagrams Draw a figure of the standard normal curve showing: a. Z(0.04) b. Z(0.94) Using Table 4B, complete the following chart of z-scores that bound a middle area of a normal distribution. Find the normal approximation for the binomial probability P(x = 6), where n = 12 and p = 0.6. Compare this to the value of P(x = 6) obtained from Table 2. From the table of random numbers in Table 1 in Appendix B, construct another table showing 20 sets of 5 randomly selected single-digit integers. Find the mean of each set (the grand mean) and compare this value with the ...Post your question
