Assume that x has a normal distribution with the specified mean and standard deviation. Find the indicated probability.
Sketch the area under the standard normal curve over the indicated interval and find the specified area. (Enter a number. Round your answer to four decimal places.) The area between z = 0.32 and z = 1.93 is 0.341 X
Suppose we have a binomial experiment in which success is defined to be a particular quality or attribute that interests us. (a) Suppose n = 28 and p = 0.33. (For each answer, enter a number. Use 2 decimal places.) n.p 26.07 n-q = 2.34 X |X
(c) Suppose n = 41 and p = 0.16. (For each answer, enter a number. Use 2 decimal places.) n.p = n.q= Can we approximate by a normal distribution? Why? (Fill in the blank. There are four answer blanks. A blank is represented by first blank Yes No ß second blank can cannot be approximated by a normal random variable because third blank O both n-p and n-q exceed On-p exceeds O n-q does not exceed O n-q exceeds O nop does not exceed n-p and n-q do not exceed X fourth blank (Enter an exact number.) Ō = What are the values of μ and o? (For each answer, enter a number. Use 3 decimal places.) μ =
