Answer:

Option f) None of these

Step-by-step explanation:

We are given the following data set:

Sample size, n = 12

Sample mean = 9.4

Sample standard deviation = 0.64

Confidence interval:

$\bar{x} \pm t_{critical}\frac{s}{\sqrt{n}}$

Putting the values, we get,

$t_{critical}\text{ at degree of freedom 11 and at}~\alpha_{0.01} = \pm 3.1058$

$9.4 \pm 3.1058(\frac{0.64}{\sqrt{12}} ) = 9.4 \pm 0.574 = (8.826,9.974)$

The amount of protein a person needs each day is proportional to his or her weight. Rod weighs 165 pounds and needs 60 grams of

lukranit [14]

The equation for this would be: $\frac{60}{165}= \frac{x}{220}$ . first you want to multiply 60 by 220, then divide the product by 165. 60 times 220 is 13,200. Now divide 13,200 by 165. This will give you 80. Todd has to eat 80 grams of protein each day to stay healthy.
