Choose one answer.

a. 5.639

b. 6.782

c. None of the other answers are correct

d. 6.305

e. 6.066

Please note that x̄ is x-bar (mean of sample).

This question has been puzzling me. At first I thought there was an error because only 4 numbers are listed but it says there sample size is 5. But, this is a valid question.

So, I'm going to need the x5- x̄ value in order to calculate the standard deviation.

This is where I'm lost... could someone please provide some assistance?

Thank you so much for your time.
