Answer:

Option C is correct

Step-by-step explanation:

Given that The owner of a movie theater wants to survey theater customers about their favorite types of movies.  

If he surveys every 10th man that will not be a random sample and hence need not represent the population.

If only 25 teenagers are surveyed then opinion would be biased because of their age and will not represent the full population.

C) 50 randomly selected people leaving the movie theater  

is the correct method of survey since 50 is a reasonable sample size for public going out from theatre and also all type of people are covered here.

D) 10 women waiting in line to buy movie tickets  

is false because they are only women and also they are still waiting to get tickets.

So Option C is right.

identify the type i error and the type ii error that corresponds to the given hypothesis. the proportion of people who write wit
djverab [1.8K]

Type I error is:

" Reject the claim that the proportion of people who write with their left hand is 0.29 when the proportion is actually 0.29 "

Type II error is:

"Fail to reject the claim that the proportion of people who write with their left hand is 0.29 when the proportion is actually different from 0.29 "

<u>What is proportion?</u>

An equation in which two ratios are made equal is called a proportion. For instance, you could write the ratio as 1: 3 (for every one boy, there are three girls), which means that 14 of the population is made up of boys and 34 of the population is made up of girls.

In Statistics, a  type I error is the rejection of a true null hypothesis

and  a type II error is the non-rejection of a false null hypothesis

Given that p = 0.29 is accepted

Now type I error is

C. Reject the claim that the proportion of people who write with their left hand is 0.29 when the proportion is actually 0.29

i.e. (false positive)

and type II error here is

B. Fail to reject the claim that the proportion of people who write with their left hand is 0.29 when the proportion is actually different from 0.29.
