Sample statistics to calculate confidence interval

Reference no: EM1386283

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 a group of computers and use the sample statistics to calculate a 95% confidence interval of (-10.95, -1.5). This interval estimates the difference of (average boot time (HDD) - average boot time (SSD)). What can we conclude from this interval?

1) We are 95% confident that the difference between the two sample means falls within the interval.

2) We do not have enough information to make a conclusion.

3) There is no significant difference between the average boot time for a computer with an SSD drive and one with an HDD drive at 95% confidence.

4) We are 95% confident that the average boot time of all computers with an SSD is greater than the average of all computers with an HDD.

5) We are 95% confident that the average boot time of all computers with an HDD is greater than the average of all computers with an SSD.
