Question 8 (1 point) The owner of a local golf course wants to estimate the difference between the average ages of males and females that play on the golf course. He samples a group of men and women and then uses the sample statistics to calculate a 95% confidence interval of (3.71, 19.29). This interval estimates the difference of (the average age of men - the average age of women). What can we conclude from this interval? (1) We are 95% confident that the average age of all men who play at the course is greater than the average age of all women. 2) We do not have enough information to make a conclusion. ( 3) We are 95% confident that the difference between the two sample means falls within the interval. (4) There is no significant difference between the average age of men and women that play at the course at 95% confidence. ( 5) We are 95% confident that the average age of all women who play at the course is greater than the average age of men
