Question 5 For a standard normal distribution, determine the probability that z is greater than -0.38. Question 6 A random variable follows a normal distribution with a mean of 126 and a standard deviation of 26. What is the probability that a randomly selected value from this population is less than or equal to 140?
Question 7 A random variable follows a normal distribution with a mean of 126 and a standard deviation of 26.
