Question 7 (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 randomly samples 21 men and 23 women that play on his course. He finds the average age of the men to be 47.674 with a standard deviation of 5.205. The average age of the women was 40.805 with a Candard deviation of 6.203. If a 99% confidence interval is calculated to estimate the difference between the two average ages, what is the margin of error? Assume both population standard deviations are equal 1) 1.73530535 2) 2.69806619 3) 4 197 ( 4) 4.682 5) 4 47 Question B (1 point) It is believed that using a solid state drive (SSD) in a computer results in faster boot times when compared to a computer with a traditional hard disk (HDD). You sample 13 computers with an HDD and note a sample average of 29.595 seconds with a standard deviation of 5.8151 seconds. A sample of 9 computers with an SSD show an average of 10.351 seconds with a standard deviation of 2.3657 seconds. Construct a 95% confidence interval for the difference between the true average boot times of the two types of hard drives. Assume the difference will represent (HDD-SSD) and that the population standard deviations are statistically the same. 1) (-1.133, 39.621) 2) (15.21, 23.278) 3) (14.951, 23.537) ( 4) (17.186, 21.302) 5) We only have the sample means, we need to know the population means in order to calculate a confidence interval
