The data below shows 6 daily pH level measurements of a fish tank. 698,7.24,7.35, 7.15, 7.57,7.4 Using the sample mean, z-728, of this data ch of the following is the 96% confidence interval to est nate ? the mean daily pH level of the fish tan ? Margin of error is accurate to 3 dec mal places. 07.28 ± 0.224 07.28 ± 0.091 07.284 0.016 7.28 0.236 7.28 + 0.096 Note: Use 3 decimal places for te and 2 decimal places for s.Explanation / Answer
We calculate the margin of error , put the data in excel range from A1:F1
E = (T.INV(0.98,5)*STDEV.S(A1:F1))/SQRT(6)
= 0.236
So, option d is correct
