<h3>Answer: B) 2.9 approximately</h3>
==================================================
Explanation:
The weird or fancy looking E symbol is the greek uppercase letter sigma. It is effectively the english version of S to represent summation. So we add up all the terms to get this. Luckily this has already been done for us in the table where they wrote "sum = 34", so
From here, we substitute this into the formula, along with n = 5 since there are 5 items in the original list
So,
This computes the sample standard deviation. To get the population standard deviation, you'd basically change the "n-1" to simply "n", and the rest of the formula is identical.
The right answer is Option B: f(4) = 38
Step-by-step explanation:
Given function is;
For finding f(4), we will put x=4 in the given function; therefore
Putting x=4 in given function,
Therefore;
f(4) = 38 in the given function.
The right answer is Option B: f(4) = 38
