Question 5 Next About 10% of the population has a particular genetic mutation. 300 people are randomly selected. Find the mean for the number of people with the genetic mutation in such groups of 300. Question 6 About 9% of the population has a particular genetic mutation. 500 people are randomly selected. Find the standard deviation for the number of people with the genetic mutation in such groups of 500. Question 7 Assume that a procedure yields a binomial distribution with a trial repeated n = 5 times. Use either the binomial probability formula (or a technology like Excel or StatDisk) to find the probability of k = 5 successes given the probability q = 0.79 of failure on a single trial. (Report answer accurate to 4 decimal places.) P(X = k) = Question 9 The scores on a standardized test are normally distributed with a mean of 115 and standard deviation of 5. What test score is 2.2 standard deviations below the mean? Question 10 < > A normal distribution has a mean of 133 and a standard deviation of 4. Find the z-score for a data value of 131. Round to two decimal places
