Question

The following data are costs (in cents) per ounce for nine different brands of sliced Swiss cheese.

28 63 39 42 70 81 46 52 49

Compute the variance for this data set. (Round your answer to three decimal places.)

Answer 1

To compute the variance for the given data set, follow the steps: find the mean, subtract the mean from each data point, square the result, find the sum of squared differences, and divide by the number of values.

Step-by-step explanation:

To compute the variance for this data set, we need to follow these steps:

1. Find the mean (average) of the data set by adding up all the values and dividing by the number of values.
2. Subtract the mean from each data point and square the result.
3. Find the sum of all the squared differences.
4. Divide the sum by the number of values (in this case, 9) to get the variance.

By following these steps, we can compute the variance for the given data set.
