Confidence Interval: (0.44,1.00)

Step-by-step explanation:

We are given the following data set:

0.60, 0.74, 0.09, 0.89, 1.31, 0.51, 0.94

Formula: where are data points, is the mean and n is the number of observations.  Sum of squares of differences = 0.8809 90% Confidence interval: Putting the values, we get,  No, it does not appear that there is too much mercury in tuna​ sushi.
