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
Answer to relevant QuestionsDraw a figure of the standard normal curve showing: a. Z(0.15) b. Z(0.82) Using Table 4A and the symmetry property of the normal distribution, complete the following charts of z-scores. The area given in the tables is the area to the right under the normal distribution in the figures. a. z-scores ...Understanding the z notation, z(a), requires us to c. z(100 — 001) d. z (0.025) — z (0.975) know whether we have a z-score or an area. Each of the following expressions uses the z notation in a variety of ways, some ...Referring to Example 6.21 (p. 302): a. Calculate P(x < 3|B(25, 3 )). b. How good was the normal approximation? Explain. a. Use a computer to draw 500 random samples, each of size 20, from the normal probability distribution with mean 80 and standard deviation 15. b. Find the mean for each sample. c. Construct a frequency histogram of the ...
