Question

A) Construct the confidence interval for the population mean μ. c=0.98​, (overbar)  x=7.6​, σ =0.7 and n=48

A 98​% confidence interval for μ is ( , )

B) Construct the confidence interval for the population mean μ. c=0.90 (overbar) x=16.2​, σ=2.02 and n=70

A 90​% confidence interval for μ is ( , )

C) Use the confidence interval to find the margin of error and the sample mean. left parenthesis 0.144 comma 0.280 right parenthesis (0.144,0.280)

The margin of error is

D) Use the confidence interval to find the margin of error and the sample mean. left parenthesis 1.64 comma 1.88 right parenthesis (1.64,1.88)

The margin of error is

E)Use the confidence interval to find the estimated margin of error. Then find the sample mean. A biologist reports a confidence interval of left parenthesis 3.7 comma 4.9 right parenthesis(3.7,4.9) when estimating the mean height​ (in centimeters) of a sample of seedlings

The estimated margin of error is

F) Use the confidence interval to find the estimated margin of error. Then find the sample mean. A store manager reports a confidence interval of left parenthesis 45.8 comma 82.4 right parenthesis(45.8,82.4) when estimating the mean price​ (in dollars) for the population of textbooks.

The estimated margin of error is
