Let X be a normal random variable with a mean of -0.62 and a standard deviation of 2.45. a)The z-score that corresponds to a particular data point (x) is 1.13. Calculate the data point. Give your answer to 2 decimal places. x = b)The area under the standard normal probability density function from negative infinity to 1.13 is interpreted as the probability that X is: less than or equal to x equal to x greater than or equal to x
