Assume that z-scores are normally distributed with a mean of 0 and a standard deviation of 1. If P(z> d) = 0.9911, find d. d= (Round to two decimal places.)
Assume that z-scores are normally distributed with a mean of 0 and a standard deviation of 1. If P(0<=<a) = 0.4484, find a. a = (Round to two decimal places.)
Assume that z-scores are normally distributed with a mean of 0 and a standard deviation of 1. If P(-b<z<b) = 0.887, find b. (Round to two decimal places.) Hint: Consider symmetry on this problem and draw a picture of the normal distribution to visualize this problem. What is the area under the normal curve from -b to b? (given in the problem) • What is the area under the normal curve that is NOT between -b and b? (Complement of the answer to the first part of the hint) . Given that information, what is the area under the normal curve from -∞o to-b? (Use symmetry of normal distribution.) . Given that information, what calculator function can you use to find -b? • Now find b.
