Answer Happy

Assume that x has a normal distribution with the specified mean and standard deviation. Find the indicated probability. (Enter a number. Round your answer to four decimal places.) μl = 20; σ = 4.4 P(x ≥ 30) = X
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 =
