In this question set you will be using StatKey to conduct randomization tests for a single proportion. A STAT 200 instructor wants to know if more than half of online students use the eTextbook. Conduct a randomization test given that 8 students in a random sample of 12 use the eTextbook.

What type of test would you use and what is the hyothesis? What is the p-value? Do you reject or fail to reject the null hypothesis?

Answer #1

Given : n=12 , x = 8

Therefore , the sample proportion , p = x / n = 8 / 12 = 0.6667

a ) Hypothesis : VS

b) The test statistic under Ho is ,

c ) P-value = ; From normal probability table

d ) Decision : Here , P-value = 0.1251 >

Therefore , fail to reject the null hypothesis at significance level.

e ) Conclusion : Hence , there is not sufficient evidence to conclude that the more than half of online students use the eTextbook.

Confidence Intervals & Hypothesis Tests The manager of a restaurant wants to know if there is a correlation between the amount of a customer’s bill and the percent that they tip. In other words, as people spend more money, do they tend to tip at different rates? With data from a random sample of 157 receipts, he used StatKey to construct a 95% bootstrap confidence interval for r. The results were: [0.018, 0.292]. A. If the manager wanted to conduct...

Questions D-F d) You conduct a hypothesis test for the population proportion. After you calculate the z test statistic, you find that your p-value = 0.059. Using alpha (α) = 0.05 level of significance, what is your decision regarding the null hypothesis? Choose from the following. - Reject the null hypothesis and reject the alternative hypothesis - Accept the null hypothesis - Do not reject the null hypothesis - Reject the null hypothesis and accept the alternative hypothesis e) You...

A group of researchers wants to examine whether taking multiple practice quizzes improve scores on tests. They compare the exam scores for a sample of n1 = 12 students who took multiple practice quizzes with the test scores of a sample of n2 = 10 students who did not do any practice quizzes. Results of the study revealed that the practice quiz group had M1 = 95, SS1 = 52. The no quiz group had M2 = 92, SS2 =...

Multiple Choice: How often do you go out dancing? This question was asked by a professional survey group on behalf of the National Arts Survey. A random sample of 95 single men showed that 24% went out dancing occasionally. Another random sample of 92 single women showed that 21% went out dancing occasionally. Is the proportion of single men who go out dancing occasionally higher than the proportion of single women? Use a 5% level of significance. If men are...

For this project, you will make decisions about how two parameters (proportions or means) compare using hypothesis tests, and you will estimate the difference between the two parameters using confidence intervals. For each confidence, report the following: the confidence interval limits rounded as directed (from StatCrunch) An interpretation of the confidence interval (e.g. "I am 95% confident ... .") Here is a template for reporting the answer for a sample confidence interval problem. Sample problem: Find a 90% confidence interval...
