Arandom sample of 400 michigan state university (msu) students were surveyed recently to determine an estimate for the proportion of all msu students who had attended at least three football games. the estimate revealed that between .372 and .458 of all msu students attended. given this information, we can determine that the confidence coefficient was approximately:

The confidence coefficient was approximately .

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of , and a confidence coefficient , we have the following confidence interval of proportions.

The lower end of the interval is given by:

The upper end of the interval is given by:

We have that:

The value of is the midway point between the lower and the upper end. So

The upper end is 0.458. So we can find z

don't know what that says sorry i can't you

step-by-step explanation:

idk what it says

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
