A certain chromosome defect occurs in only 1 in 230 adult Caucasian males. A random sample of n = 100 adult Caucasian males is to be obtained. (a) What is the mean value of the sample proportion p, and what is the standard deviation of the sample proportion? (Round your answers to four decimal places.) mean standard deviation (b) Does have approximately a normal distribution in this case? Explain. (Select all that apply.) the sampling distribution of p is approximately normal O the sampling distribution of p is not approximately normal Onp is less than 10 Onp equals 10 np is greater than 10. On(1 p) is less than 10. On(1 p) equals 10 On(1-p) is greater than 10 (c) What is the smallest value of n for which the sampling distribution of p is approximately normal? (Round your answer to the nearest whole number.) n = adult Caucasian males

Suppose that a particular candidate for public office is in fact favored by 48% of all registered voters in the district. A polling organization will take a random sample of 250 voters and will use p, the sample proportion, to estimate p. What is the approximate probability that will be greater than 0.5, causing the polling organization to incorrectly predict the result of the upcoming election? (Round your answer to four decimal places.) USE SALT
