What is the probability that Z is equal to or greater than 0.6? Z represents a standard normal continuous random variable. Answer: The probability that Z is greater than b is 55%. What is b? Z represents a standard normal continuous random variable. Answer:
The general philosophy of standardizing is that standardizing a random variable involves a. Subtracting the main in the batting by the standard deviation b. Dividing the standard deviation of the total of successes by the total of trials c. Adding and subtracting standard deviations in each direction d. Subtracting the area in the right tail from 1 since the Z chart gives only the area "to the left"
