Comparing Two Independent Population Proportions

For this question assume the population is at least 20 times larger than the sample size. The null hypothesis is that the proportions from A and B are equal.

The numbers you need to answer the questions are nA = 16 , nB = 22 ,

p' A  is 0.5625 and xB = 6

Find xA    This needs to be whole number.

Find p'B   Round to 4 decimal places

Find the pooled proportion. pc  =   to 4 decimal places

Find the test statistic z=   Round to 3 places.

Find the P-value for a two tail test.   Use rounded version of z to two places. Then round the P-value to 3 places.

When comparing two sample proportions with a​ two-sided alternative​ hypothesis, all other factors being​ equal, will you get a smaller​ p-value if the sample proportions are close together or if they are far​ apart? Explain. Choose the correct answer below. A. The​ p-value will be smaller if the sample proportions are far apart because a larger difference results in a larger absolute value of the numerator of the test statistic. B. The​ p-value will be smaller if the sample proportions...

5. We want to know whether the difference in the population proportions between group 1 and group 2 is greater than 0. Specifically, we want to test H0 : p1−p2 ≤ 0 versus Ha : p1−p2 > 0. We know that 264 of the 514 observations in group 1 have the characterisitic. And, we know that 245 of the 518 observations in group 2 have the characterisitic. (a) What is the sample proportion for group 1? (round to 5 digits...
