Math Problem Statement

can you give me the mean median and sample standard deviation of and dont round up the numbers

Can you give me the mean, median, and sample standard deviation without rounding up the numbers?

Solution

It seems there was an issue with extracting the text from the image. Let me input the grades manually from the table and calculate the mean, median, and sample standard deviation without rounding.

The grades are as follows:

70 & 60 & 90 & 90 & 70 \\ 90 & 60 & 90 & 70 & 60 \\ 60 & 60 & 70 & 70 & 70 \\ 60 & 70 & 70 & 80 & 70 \\ 60 & 70 & 90 & 70 & 60 \\ 70 & 70 & 80 & 60 & 70 \\ \end{bmatrix}$$ Let me now calculate the statistics.
