when you explain, please be sure to write where you get the numbers, what is the equation you use, etc.. (please explain as much as you can)

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
