B. What are the conditions required to use this test? Have the conditions been satisfied? Explain.

Answers

Answer 1

Answer: We use a chi-square test of homogeneity, as we have a single categorical variable measured within two different populations.

The requirements for this test are that we have two simple random samples (this is clearly satisfied, given that we are sampling all students who take the class that year) and that the expected value for each cell, defined as the cell's row sum multiplied by the column sum divided by the sum of all values in the dataset, is greater than 5. This is satisfied simply by testing for each value in the table.

You are going to mix a gallon bucket of window cleaner. The instructions direct you to mix 1 part cleaner to 3 parts water. How much cleaning solution will you need to use?

Answers

You have a bucket 1 gallon big.
To mix cleaner and water you need to divide the bucket's capacity into 4.
It's easy in this case as gallon is divided into quarts (1 gallon is equal to 4 quarts).
Since one part will be a window cleaner, it means that you will need to use 1 quart of the cleaner.

Three friends are selling items at a bake sale. May make $23.25 seeking bread. Inez sells gift baskets and makes 100 times as much as May. Carolyn self pies and make one tenth of the money Inez makes. How much money does each friend make.

Answers

The amounts earned by the three friends are:

May: $ 23. 25 selling bread.
Inez: $ 2, 325 selling gift baskets.
Carolyn: $ 232. 50 selling pies.

How to find the amounts earned ?

May makes $23.25 selling bread.

Inez makes 100 times as much as May. So, Inez makes:

= $ 23. 25 ( what May make s) * 100

= $ 2, 325 selling gift baskets.

Carolyn makes one - tenth ( 10 % ) of the money Inez makes. So, Carolyn makes:

= 10 % of $ 2, 325 (what Inez makes)

= ( 0.10 * $ 2, 325 )

= $ 232. 50 selling pies

#SPJ3

MAY = $23.25

INEZ= 100 times as much as May
So May makes ; 23.25 * 100 =$2325

CAROLYN= 1/10 of the money Inez makes
So Carolyn makes ; 2325 * 1/10 = 2325 / 10 = $232.5

Hope that helps.
