Question

The number of daily customers at Good Eats Diner for one week was {70, 68, 110, 65, 90, 125, 105).What is the

population standard deviation to one decimal place?

Answer 1

To calculate the population standard deviation: find the mean, subtract the mean from each number, square each difference, find the mean of the squared differences, and take the square root of the mean of the squared differences.

Step-by-step explanation:

To calculate the population standard deviation, follow these steps:

1. Find the mean of the data set by adding up all the numbers and dividing by the total count of numbers.
2. Subtract the mean from each number in the data set to find the difference.
3. Square each difference.
4. Find the mean of the squared differences.
5. Take the square root of the mean of the squared differences.

Applying these steps to the given data set, the population standard deviation is approximately 22.8 to one decimal place.
