Question

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

Answer 1

Probability of successes or proportion 'p' =0.1818

q = 0.8182

Given sample size 'n' =275

we will use binomial distribution

`P(X=r) = n_{C_(r) } p^(r) q^(n-r)`

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

`p = (x)/(n) = (50)/(275) = 0.1818`

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

`P(X=r) = n_{C_(r) } p^(r) q^(n-r)`
