The owner of a golf course wants to determine if his golf course is more difficult than the one his friend owns. He has 27 golfers play a round of 18 holes on his golf course and records their scores. Later that week, he has the same 27 golfers play a round of golf on his friend's course and records their scores again. The average difference in the scores (treated as the scores on his course - the scores on...
thank you for all your help this means a lot to me 1 2 Entered Answer Preview Result Message 1110 1110 incorrect Your answer needs to be rounded to the next largest whole number. The answer above is NOT correct. (1 point) Suppose we want a 95% confidence interval for the average amount spent on books by freshmen in their first year at college. The amount spent has a normal distribution with standard deviation $34. How large should the sample...
Ashbrook Golf Course wants to estimate the mean time for a round of golf for all golfers at their course. They wish to estimate the population mean time with a margin of error of 1.85 minutes. The standard deviation from a small pilot study is estimated at 11.15 minutes. What minimum sample size should Ashbrook use if they want to be 95% confident of the result? (Remember your units) (2 points) D eC - Format VBI U - n =...
The average score of all golfers for a particular course has a mean of 66 and a standard deviation of 5. Suppose 100 golfers played the course today. Find the probability that the average score (a) Find the mean of the sampling distribution for the average score (sample mean) of 100 golfers. Round answer to the nearest integer. Do NOT include the zero before the decimal point. Mean = ____ (b) Find the standard deviation of the sampling distribution...

Question 7 (1 point) The owner of a local golf course wants to determine the average age of the golfers that play on the course in relation to the average age in the area. According to the most recent census, the town has an average age of 55.89. In a random sample of 30 golfers that visited his course, the sample mean was 45.84 and the standard deviation was 6.514. Using this information, the owner calculated the confidence interval of...
