A teacher wants to determine why students signed up for his summer statistics class. He asked a randomly selected 50 (of the 275) registered to select one of four reasons (convenience, liked his teaching style, needed it to graduate, or other) on an online quiz. Identify the experimental unit of interest to this problem

Probability of successes or proportion 'p' =0.1818

                                              q = 0.8182

Given sample size 'n' =275

we will use binomial distribution

Step-by-step explanation:

Explanation:-

Given data number of students 'n' = 275

He asked a randomly selected 50 (of the 275) registered to select one of four reasons (convenience, liked his teaching style,needed it to graduate , or other)

Probability of successes or proportion

conclusion:-

The experimental unit of interest to this problem

Probability of successes or proportion 'p' =0.1818

                                                     q = 1-p = 1- 0.1818 = 0.8182

Given sample size 'n' =275

we will use binomial distribution

4.08%

step-by-step explanation:

to determine the unit cost your would divide the total cost by the number sold.

5 bagels for $3.60         $3.60/5 = $.72 each at value mart
