Question: Using the z a notation identify the value of a used
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
Relevant QuestionsUsing 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. We are often interested in finding the value of z that bounds a given area in the right-hand tail of the normal distribution, as shown in the accompanying figure. The notation z(a) represents the value of z such that P(z > ...a. Find the area under the normal curve for z between z(0.95) and z(0.025). b. Find z(0.025) - z(0.95). Find the normal approximation for the binomial probability P(x = 4, 5), where n = 14 and p = 0.5. Compare this to the value of P(x = 4, 5) obtained from Table 2. a. Using a computer or a random number table, simulate the drawing of 100 samples, each of size 5, from the uniform probability distribution of single-digit integers, 0 to 9. b. Find the mean for each sample. c. Construct ...
