Chapter 07, Section 7.4, Intelligent Tutoring Problem 031 Let x be a continuous random variable that has a normal distribution with p = 75 and o = 11. Assuming ns 0.05N, where n = sample size and N = population size, (a) Compute the mean, HF of I. = If (b) Compute the standard deviation oz of I. Round your answer to four decimal places. Chapter 07, Section 7.4, Intelligent Tutoring Problem 031 Let x be a continuous random variable that has sample of 18 taken from this population will be between 69.61 and 77.23. normal distribution with p = 75 and o = 11. Assuming n s 0.05N, wheren = sample size and N = population size, find the probability that the sample mean, X, for a random Recall the following from section 7.3 & 7.4 of the text. If the population from which the samples are drawn is normally distributed, then the mean uz of the sampling distribution of I is equal to the mean of the population, p. That is, H = H. The standard deviation o; of the sampling distribution of I, mean of the sample is given by the formula o = Vn where n is the sampling size and o is the population standard deviation provided the sample size is small in comparison to the population size. Sample size is considered to be small compared to the population size, if ns 0.05N (sample size is less than or equal to 5% of the population). Furthermore, if the population from which the samples are drawn is normally distributed then the sampling distribution of I will also be normally distributed irrespective of the sample size. The z value for a value of I is calculated as z=
