Question 1086889: a) determine which distribution you would use to determine the critical value (normal distribution, t distribution, or neither) and state the critical value
b) calculate the margin of error for the given confidence level if possible. If this is not possible, indicate what would be required in order to perform the calculation
Normally distributed population with σ = 40, n = 20, 98% confidence level.
You can put this solution on YOUR website! Normal distribution with known sd.
98% CI uses z=2.33
interval width is +/-2.33*40/sqrt (20)=+/-2.33*8.94=+/-20.84
