Based on the table, the equation of the line of best fit to the nearest thousandths is equal to y = 1.671x + 4.699.
<h3>How to determine the equation of the line of best fit?</h3>Mathematically, the equation of the line of best fit is calculated by using this formula:
y = mx + c
<u>Where:</u>
- m is the slope.
- c is the intercept.
Based on the table, the slope and intercept to the nearest thousandths are equal to 1.671 and 4.699 respectively.
Therefore, the equation of the line of best fit is equal to y = 1.671x + 4.699.

Answer:
Step-by-step explanation:
The standard deviation is the square root of the variance, and the variance is found by using the mean. So we will do that first. I will use the population variance as opposed to the sample variance since our set of numbers is small.
The mean: 8 + 12 + 15 + 17 + 18 = 70 and divide that by 5 to get
and use this to find the variance in the formula:
it is a bit difficult to enter that formula in correctly, but here's how it works mathematically:
Squaring this ensures us that we don't end up with zero, which would be useless.
so
which means that the standard deviation is
s = 3.633
(If you do it with n-1 = 4 in the denominator of the variance, you get a standard deviation of 4.062)
