Sample mean: x = 2534.9(round to at least 4 decimals)

Sample standard deviation:s = 1425.6075(round to at least 4 decimals)

Size of your sample:n = 50

Standard error:s_{x = = 1425.6075/50=201.6114}

(Show work, then round to at least 4 decimals)

1)What is your Point Estimate?(round each answer to at least 4 decimals)

For an 84% confidence interval:Point estimate = 2534.9

For an 91% confidence interval:Point estimate = 2534.9

For a 96% confidence interval:Point estimate = 2534.9

2.)

a.For this project, use the link below to find your exact t_c

i.Go to https://www.danielsoper.com/statcalc/calculator.aspx?id=10

ii.Type in your degrees of freedom (n-1)

iii.Type in your probability level

1.84% CI will have a probability level of 0.16.

2.91% CI will have a probability level of 0.11.

3.96% CI will have a probability level of 0.06.

iv.You will use the two-tailed answer (not the right-tailed)

For an 84% confidence interval:t_c = (round answer to at least 4 decimals)

For an 91% confidence interval:t_c = (round answer to at least 4 decimals)

For a 96% confidence interval:t_c = (round answer to at least 4 decimals)

3)What is your margin of error?

Show work

(round each answer to at least 4 decimals)

For an 91% confidence interval:E =

For a 96% confidence interval:E =
