Why does my answer to this question (attached Image) always evaluated as incorrect? I have tried both population variance and sample variance with two decimal places. Divided by n-1 as it is a sample variance problem. All the time this shows incorrect.
This may be a defective quiz question. Try it using ‘n’ instead of ‘n-1’.
Please reply with whether this worked.
I think so. I have tried for both n and n-1. Also, take 1 or 2 decimals but it didn’t work.
Please show your math for how you are doing the calculation.
Thank you for your quick responses. That was not a defective quiz. I was doing that wrong. I have solved that question successfully. If you want, I can share my solution but I fear that might violate the community guidelines.
Thanks for your update.
