#2: Beyond the Numbers 3.29-Questions 1 and 2 (with alterations) For both questions, state: 1. The null and alternative hypotheses 2. The sample proportion 3. The test statistic 4. The p-value (please provide a screenshot) 5. If there is enough evidence to reject Ho (Do-not say whether you chose HA or not). Use Statkey to find each p-value, and copy screenshots showing the p-values into your assignment. Each screenshot should contain a graph of the appropriate theoretical distribution, and the parameters toward the right of the screen need to be visible. (In other words, don't crop the parameters out.) The data set for question 2 can be found on page 363 of the workbook

Explanation / Answer

total number of people who survived more than 1 year =27

proportion = .4285

n= 63

ho: Survival proportion is less than .4

Ha: survival proportion is greater than .4

we calculate the test statistic

1-sample proportions test with continuity correction

data: 27 out of 63, null probability 0.4

X-squared = 0.11177, df = 1, p-value = 0.3691

alternative hypothesis: true p is greater than 0.4

95 percent confidence interval:

0.3236756 1.0000000

sample estimates:

p

0.4285714

so we can say at .05 the survival rate is greater the .4
