Question 20 2.5 pts Texas has roughly 225,000 farms, more than any other state in the United States. The actual mean farm size is u = 582 acres (sample mean = 582) and the standard deviation is o = 150 acres. For random samples of n = 100 farms. . find the standard deviation of the distribution of sample means. . What is the probability of selecting a random sample of 100 farms with a mean greater than 600 acres? O s = 15, p =.12 O s= 10, p = .88 O s= 15, p = 0.88 O s= 10, p = .12 Question 21 2.5 pts Find the 95% confidence interval for the protein intake sample of n = 300 men, which has a sample mean (Xbar) of 77 grams and a standard deviation of s= 58 grams
