Answer:
Step-by-step explanation:
The slope is found by doing the equation . When looking at the first two points, it's shown that the rise (difference between the two y values) is -9 (since it decreased by 9) and the run (difference between the two x values) is 8 (since it increased by 8). This makes the slope equal
.
The y intercept is found by looking at the y value when x = 0. In this picture, it is clear that it is 7.
The equation you want to use is y = mx + b , where b is the y intercept and m is the slope. Just plug in the numbers and you got your equation!
Answer:
standard error of the mean (S.E) = 0.06
Step-by-step explanation:
<u><em>Explanation:</em></u>-
Given sample size 'n' = 500
Given variance of the Population = 900
The standard deviation of the Population = √900 = 30
The standard error of the mean is determined by
