A class had a large bin of animal crackers. Each student selected a random sample of 20 crackers and recorded the percent that were elephants. Construct a dot plot of the following results, 20 5 15 15 10 25
10 15 15 20 25 5
a. Describe the shape and variability

b. Estimate a population mean

c. What would the dot plot look like if each student used a sample of 50 random pieces?

question

what is the value of the third quartile of the data set represented by this box plot? a. 19 b. 21 c. 26 d. 29

answer

c

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
