The data consists of 25 observations - this is just how many people were involved in the study. (count the rows, excluding the header)

42 to ^5 is standard form
Here's the equation:
<u>4x</u> = <u>10
</u><u />4 4 You would have to divide 4 on both sides to get isolate variable.
x = 2.5
The answer for this is m
