Evaluate whether to keep funding the nutrition lunch program based on survey ratings variability.

Here are the solutions for the math items.

ITEM 2: Nutrition Lunch Program

a) Evaluate whether to keep funding the nutrition lunch.

The program will be kept only if the variability (standard deviation) of the survey ratings is at most 1.2.

Step 1: Calculate the mean ($\bar{x}$) of the ratings.
The survey results are: 3 rated 1, 10 rated 2, 12 rated 3, 5 rated 4, 18 rated 5.
Total learners surveyed = $3 + 10 + 12 + 5 + 18 = 48$.
