Answer:

C. The president rejects the hypothesis that the proportion of students who earn a​ bachelor's degree within six years is 0.398​, ​when, in​ fact, the proportion is 0.398.

Step-by-step explanation:

A type I error occurs if you reject the null hypothesis when it is true.

Now the hypotheses are:

H_0: The proportion is 0.398

H_1: The proportion is less than 0.398

If in actual fact the proportion is 0.398, then the president must not reject the H_0.

This is a correct decision.

If in actual fact the proportion is 0.398, and the president rejects the H_0, then a type I error is committed.

The correct choice is C.

Luke's turkey chili recipe calls for 2.5 pounds of ground turkey for every 5 servings. How many servings can he make if he has 6
alexira [117]

Answer:

12 servings

Step-by-step explanation:

Luke's turkey chili recipe calls for 2.5 pounds of ground turkey for every 5 servings. How many servings can he make if he has 6 pounds of ground turkey?

From above question:

2.5 pounds of ground turkey = 5 servings

6 pounds of ground turkey = x

Cross Multiply

2.5 × x = 6 × 5

x = 6 × 5/2.5

x = 12 servings

Hence, 6 pounds of ground turkey can make 12 servings.

Completing the explanation.

The equation is

5x = 2.5y

where:

x = represent how many pounds of ground turkey he has = 6 pounds

y = to represent how many servings he can make

Hence,

5 × 6 = 2.5y

y = 5 × 6/2.5

y = 12 servings
