ere to view the standard normal distribution table (page 1) here to view the standard normal distribution table_(page 2). scribe the sampling distribution of p. se the phrase that best describes the shape of the sampling distribution below. Approximately normal becausens0.05N and np(1 - p) < 10. Not normal because ns0.05N and np(1 - p) < 10. Approximately normal becausens0.05N and np(1 - p) 2 10. Not normal because ns0.05N and np(1- p)2 10. mine the mean of the sampling distribution of p. (Round to one decimal place as needed.) mine the standard deviation of the sampling distribution of p. (Round to six decimal places as needed.) hat is the probability of obtaining x = 55 or more individuals with the characteristic? That is, what is P(p20.44)?
