There sufficient evidence to conclude that sons their fathers at the 0.10 level of significance.Construct a confidence interval of the population proportion at the given level of confidence. x = 120, n= 1200, 98% confidence Click here to view the standard normal distribution table (page 1). Click here to view the standard normal distribution table (page 2). The lower bound of the confidence interval is (Round to three decimal places as needed.) The upper bound of the confidence interval is (Round to three decimal places as needed.)Assume the random variable X is normally distributed with mean u = 50 and standard deviation o = 7. Compute the probability. Be sure to draw a normal curve with the area corresponding to the probability shaded. P(35
