need help with statistics please!!!

This Question: 1 pt 1 of 14 (0 complete) Determine u- and o- from the given parameters of the population and the sample size. Round the answer to the nearest thousandth where appropriate. H = 69, 6 =6, n= 22 O A. Hy = 69, 6- = 1.279 O B. H- = 69, 6- =6 O C. Hy = 69, 6- = 0.273 O D. H- = 39.837, 6- = 1.279 This Question: 1 pt 2 of 14 (0 complete) D Suppose a population has a mean of 7 for some characteristic of interest and a standard deviation of 9.6. A sample is drawn from this population of size 64. What is the standard error of the mean? O A. 0.15 O B. 1.2 O C. 0.7 O D. 3.3 This Question: 1 pt 3 of 14 (0 complete) This The average score of all golfers for a particular course has a mean of 60 and a standard deviation of 4. Suppose 64 golfers played the course today. Find the probability that the average score of the 64 golfers exceeded 61. Round to four decimal places. O A. 0.1293 O B. 0.4772 O C. 0.3707 O D. 0.0228 This Question: 1 pt 4 of 14 (0 complete) This Te Assume that blood pressure readings are normally distributed with a mean of 124 and a standard deviation of 9.6. If 144 people are randomly selected, find the probability that their mean blood pressure will be less than 126. Round to four decimal places. O A. 0.0062 O B. 0.9998 O C. 0.9938 O D. 0.8615 This Question: 1 pt 5 of 14 (0 complete) Fill in the blank According to the law of large numbers, as more observations are added to the sample, the difference between the sample mean and the population mean O is inversely affected by the data added O tends to become smaller O tends to become larger remains about the same
