Answer:
For random samples of 100 seniors, 68% of the sample means fall between 340 and 520
Step-by-step explanation:
As a property of normal distribution, 68% of sample means fall between mean - sigma(430 - 90 = 340) and mean + sigma (430 + 90 = 520) (here, sigma is standard deviation).
Hope this helps!

Answer:
143 calories
Step-by-step explanation:
We can use a ratio to solve
110 calories x calories
----------------- = ---------------
28.4 grams 36.92 grams
Using cross products
110* 36.92 = 28.4 * x
Divide each side by 28.4
110*36.92 / 28.4 = x
143 calories = x
