Difference in Two Proportions

100

The mean of the difference between two proportions

What is p₁ - p₂ ​​​​

200

If we say the null hypothesis is p₁=p₂ give one example of an alternate hypothesis

What is p₁ not equal to p₂ or p₁>p₂ or p₁<p₂

300

I want to find the interval for the difference between two proportions, what standard deviation will I use?

What is the square root of ((p₁*(1-p₁))/n₁) + ((p₂*(1-p₂))/n₂)

400

What is p_c and when do we use it?

What is the combined (weighted average) of the proportions and when hypothesis testing is done

500

Calculate! Provide the P value for the following

p₁=.6 p₂=.5 n₁=200 n₂=250

the alternate hypothesis is p₁>p₂

What is P = .0174

Hypothesis Tests

100

The P value is .045 , the level of significance is .05. The action we take.

What is reject the H₀

200

Name two assumptions of performing a Hypothesis test

What is Random, 10% population, np, n(1-p)

300

I rejected the null when alpha was .1. When alpha was .05 we failed to reject. What could the P value of been?

What is a value between .1 and .05 including .05.

400

A sample size is 300, and our alpha is .05. We have a .05 chance of rejecting the null. We redo the sample with a new size of 650. With nothing else changing, what is the chance of rejecting the null?

What is .05

500

The conclusion statement of a Hypothesis test

Since the p-value <(>) alpha, I reject (fail to reject) the H₀. There is(is not) sufficient evidence to suggest that H_a

A blood test for HIV is being performed. H₀=person is well. H_a= person is sick. Which error is more serious?

What is Type I error?

400

The difference of two proportions interval between the success rate of two production lines in a factory is (-.023 , .184). Interpret the interval.

What is the interval contains 0, so it is plausible that there is no difference between the success rates of the two production lines in a factory.

500

Super challenge mode game extravagant challenge problem. Every student must complete the problem on the board. You have 5 minutes to calculate the P value between the difference of two proportions. (Points will be given by first finishers that are correct. Wrong answers will lose points) Example: 1st person done +500/-500. Second person +400/-400

What is the solution on the board
