A population of values has a normal distribution with ,u = 177.9 and 0' = 12.7. You intend to draw a random sample of size n = 207. What is the mean of the distribution of sample means? #5: What is the standard deviation of the distribution of sample means? (Report answer accurate to 2 decimal places.) 0i Suppose 7% of students are veterans and 139 students are involved in sports. How unusual would it be to have no more than 15 veterans involved in sports? (15 veterans is about 10.791496) When working with samples of size 139, what is the mean of the sampling distribution for the proportion of When working with samples of size 139, what is the standard error of the sampling distribution for the proportion of veterans? [: Compute P03 3 0.107914). NOTE: Give results accurate to 5 decimal places Is this result unusual? A Yes, there is a less than 50% chance of this happening by random variation. A No, there is at least a 50% chance of this happening by random variation. Let X represent the full height of a certain species of tree. Assume that X has a normal probability distribution with p = 205.3 ft and cr = 65 ft. You intend to measure a random sample of n = 25 trees. What is the mean of the distribution of sample means? What is the standard deviation of the distribution of sample means (i.e., the standard error in estimating the mean)? (Report answer accurate to 2 decimal places.) D m
