The decimal of 2.1 is greater than 2.0 but less than 2.42
We have been given that the distribution of the number of daily requests is bell-shaped and has a mean of 38 and a standard deviation of 6. We are asked to find the approximate percentage of lightbulb replacement requests numbering between 38 and 56.
First of all, we will find z-score corresponding to 38 and 56.


Now we will find z-score corresponding to 56.

We know that according to Empirical rule approximately 68% data lies with-in standard deviation of mean, approximately 95% data lies within 2 standard deviation of mean and approximately 99.7% data lies within 3 standard deviation of mean that is
.
We can see that data point 38 is at mean as it's z-score is 0 and z-score of 56 is 3. This means that 56 is 3 standard deviation above mean.
We know that mean is at center of normal distribution curve. So to find percentage of data points 3 SD above mean, we will divide 99.7% by 2.

Therefore, approximately
of lightbulb replacement requests numbering between 38 and 56.
Answer:
The answer is: $13,166.67 total sales.
Step-by-step explanation:
First, Vinny receives $400 base pay - this information is not needed to solve the problem.
To find the total sales, divide $790 by 6%:
$790 / .06 = $13,166.67
You can prove this is the answer by multiplying $13,166.67 times 6%:
$13,166.67 * .06 = $790.
