A Stats Professor student asks:

Hi,

I found an error in the homework. This is from chapter 4 problem number 11. The answer should be -.50. I worked it a few times as the answer listed shows -.17. I checked a problem from stats professor that matched. -.17 is not correct.

Thank you,

Julie Cisneros
