Exhibit 12-4 in the past, 35% of the students at abc university were in the business college, 35% of the students were in the liberal arts college, and 30% of the students were in the education college. to see whether the proportions have changed, a random sample of 300 students from abc university was selected. ninety of the sample students are in the business college, 120 are in the liberal arts college, and 90 are in the education college. refer to exhibit 12-4. this problem is an example of a select one: a. test for independence b. multinomial population c. normally distributed variable d. uniformly distributed variable

b. multinomial population

Step-by-step explanation:

The data is categorical and non-overlapping. That is, there are multiple options(either the student is in the Liberal Arts College, Business College or Education College), and he cannot be in more than one option.

So this is an example of a multinomial population.

The correct answer is:

b. multinomial population

your answer is b ^w^ hope i

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
