Use the table to determine what percent of students prefer school uniforms and what percent do not prefer school uniforms. What
Ahat [919]
16 + 4 = 20

16/20 = 80% or 4/5 (20 x 5 = 100, 16 x 5 = 80)

4/20 = 20% or 1/5 (20 x 5 = 100, 4 x 5 = 20)

The relationship is that more students do not prefer school uniforms compared to the ones that do prefer them. 

Hope this helps!

subtract 32.50 from 130.00 which equals the cost, 97.50
97.50 minus 90$ is 7.50, therefore that is the answer

Select Proportional or Not Proportional to correctly classify each pair of ratios.Proportional or Not Proportional 7/8 and 42/4
Yakvenalex [24]
Based on the given fractions above which are 7/8 and 42/4, in order for us to know if they are both proportional is to do the cross multiplication. Let's say, we multiply 4 by 7 and we get 28. Divide 28 by 8 and the result is 3.5 and not 42. Therefore, we can say that these fractions are NOT proportional. Hope this helps.

nignag [31]

Answer:

a. A two-sample z-test for a difference in sample proportions

Step-by-step explanation:

We are told that there are two supermarkets in the research named X and Y.

That a random number of shoppers were selected in each supermarket.

Thus means we have two different sample proportion.. Since a different number of people were randomly selected from each supermarket and a different number of people purchased the product.

Thus, we will have 2 sample proportions one for supermarket X and the other for supermarket Y.

In addition, the position of the product was different in both supermarkets.

Thus, we can say that this is a 2 sample Z-test for difference in their sample proportion.
