6. the mean number of hours of flying time for pilots at continental airlines is 37 hours per month (the wall street journal, february 25, 2003). assume that this mean was based on actual flying times for a sample of 49 continental pilots and that the sample standard deviation was 8.2 hours. 6a. at 95% confidence, what is the margin of error? solution 5b. what is the 95% confidence interval estimate of the ub

The marginal error is 2.355

Confidence interval is

The LB and UB are 34.645 and 39.3555 respectively.

Step-by-step explanation:

Consider the provided information.

n = 49, s = 8.2 c = 95%and

Degree of freedom is: n-1 = 49-1 = 48.

From the table

Marginal error is:

Hence, the marginal error is 2.355.

Part (B)

95% confidence interval estimate

Thus, the LB and UB are 34.645 and 39.3555 respectively.

this is a very good question

step-by-step explanation:

i got a hair cut today from my mom not to flex just to flex kim jon un is one rad fellow i'd say you'd need to take the hairline in kinda like a box shape like someone rammed a lego brick into your head. from there you really need to take the top up keeping with that boxy aesthetic, finally coat the whole thing with gel if your country economics are failing or whatever you can just coat it with the starving children's food rations. about 5 orphans per strand is a good ratio. good luck with the fresh cut my dude

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
