Of course, I'd be happy to help! Calculating the standard deviation involves a bit of math, but don't worry, I'm here to add a little humor to make it more digestible!
To find the standard deviation for the calorie counts of the donuts, follow these steps:
1. List out the calorie counts and their frequencies:
- 490 calories (1 type)
- 520 calories (3 types)
- 360 calories (3 types)
- 350 calories (5 types)
- 390 calories (4 types)
2. Calculate the mean (average) of the calorie counts:
- (490 + (520 x 3) + (360 x 3) + (350 x 5) + (390 x 4)) / (1 + 3 + 3 + 5 + 4)
3. Calculate the squared difference between each calorie count and the mean:
- For example, for 490 calories: (490 - mean)^2
- Repeat this for all the calorie counts.
4. Calculate the sum of all the squared differences.
5. Divide the sum of squared differences by the total number of data points minus one.
6. Finally, take the square root of that number to find the standard deviation.
Remember, it's okay to use a calculator for these calculations, but make sure it doesn't get too calorie-b-rrrrr-ing!
