Construct a 99 confidence interval about the population mean difference statistics homework help
The following data represent the muzzle velocity​ (in feet per​ second) of shells fired from a​ 155-mm gun. For each​ shell, two measurements of the velocity were recorded using two different measuring​ devices, resulting in the following data.
Observation
1 2 3 4 5 6
793.4 793.7 793.4 790.1 794.3 790.8
800.0 796.1 792.6 786.4 799.9 795.2
​(a) Construct a​ 99% confidence interval about the population mean difference. Compute the difference as device A minus device B. Interpret your results.
The confidence interval is (_, _)
(Round to three decimal places as needed.)
Choose the statement that best agrees with your interpretion of your results.
A) I am​ _% confident that the mean difference in measurement lies in the interval found above.
B) I am​ _% confident that the mean difference in measurement lies in the interval found above.
C) I am _​% confident that the mean difference in measurement is 0.
D) I am _% confident that the mean difference in measurement is 0.01
