Part 2 of2 9 Points: 0.5 of 1 U ave Refer to the accompanying table, which describes results from groups of 8 births from 8 different sets of parents. The random variable x represents the number of girls among 8 children. Find the mean and standard deviation for the number of girls in 8 births. a Click the icon to view the data table. The mean is p: 4 girl(s). (Round to one decimal place as needed.) The standard deviation is 6 = girl(s). (Round to one decimal place as needed.) Assume that random guesses are made for six multiple choice questions on an SAT test, so that there are n = 6 trials, each with probability of success (correct) given by p = 0.25' Find the indicated probability for the number of correct answers. Find the probability that the number x of correct answers is fewer than 4. P(X
