Question

Stream TV? ~ A Pew research study claims that: “Those with a college education are more likely than those with less education to say their primary way to watch TV is online streaming.” The poll results showed that 119 out of 340 college educated adults, and 76 out of 300 non-college educated adults said they mainly watch TV via streaming.

We want to determine if the proportion of college educated adults, who primarily watch TV via online streaming is higher than the proportion of non-college educated adults.

Notation: 1=college educated and 2=non-college educated.

To calculate the test statistic to conduct a hypothesis test for this scenario, which standard error would you use?

Question 3 options:

	p0(1−p0)n‾‾‾‾‾‾‾√p0(1-p0)n
	pˆ(1−pˆ)n‾‾‾‾‾‾√p^(1-p^)n
	pˆ1(1−pˆ1)n1+pˆ2(1−pˆ2)n2‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾√p^1(1-p^1)n1+p^2(1-p^2)n2
	pˆ(1−pˆ)(1n1+1n2)‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾√p^(1-p^)1n1+1n2

Answer 1

Solution :

This is the two tailed test .

To calculate the test statistic to conduct a hypothesis test for this scenario the standard error is ,

√ [$\hat p1$(1 - $\hat p1$ ) / n1 + $\hat p2$ (1 - $\hat p2$ ) / n2]
