95% confidence level. Using 2 sample t-test, find the margin of error, confidence interval, & sample standard deviation for the data set below. 6935, 6948, 7130, 7089, 8925, 7040, 9067, 9210, 9111, 9321, 9231, 7073, 7179,6943, 7051, 6971, 7051, 6982,6900, 6937, 7036, 9513, 11738, 10420, 10840, 11566, 10575, 11189, 11375, 11077​

Take the square root of the calculated value. Multiply the result by the appropriate z*-value for the confidence level desired. Refer to the above table for the appropriate z*-value. If the confidence level is 95%, the z*-value is 1.96.
