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 11 computers with an HDD and note a sample average of 23.105 seconds with a standard deviation of 6.4906 seconds. A sample of 10 computers with an SSD show an average of 14.463 seconds with a standard deviation of 2.3266 seconds. Construct a 90% 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.

Use of the weaving/sewing machines is believed to drive MOH costs. At the beginning of the year, the total estimated MOH cost for production of the wristbands is $68,200, and the estimated machine hours were 5,000 for Basic wristbands and 1,200 for Premium wristbands. At the end of the year you can see that 28,000 Basic wristband units and 15,000 Premium wristband units were produced. The Basic wristbands used 4,200 machine hours and Premium wristbands used 1,000 machine hours this...

A researcher wanted to know whether people drive faster in sports cars or pick up trucks. He went out on the freeway with a radar gun and track the speed of people in both types of cars. A sample of n=30 sport car drivers went an average of M=69 (s=5.35) whereas a sample n=30 pick up truck drivers wet an average of M=67 9 (s=5.30). What statistics should be run? Calculate Harlteys F-Max, one-tailed to two-tailed test, calculate confidence interval...
