You gather data from two local churches about the average offering (a monetary donation to the church)that is collected at a weekly service. You want to see whether the average offering given at one churchis the same as the average offering at another church. The number of people who attend Church 1 is201, and the average amount offered is $12.50. The number of people who attend Church 2 is 350, andthe average amount offered is $11.87. The sample standard deviations for Church 1 and Church 2 are$3.15 and $4.57, respectively. (a) What is the hypothesis you want to test? (b) Calculate the test statistic and test your hypothesis at the 95 and 99 percent confidence levels. (c) Pretend that the sample means and standard deviations remain the same, but that the numberof people sampled at Church 2 was 201 instead of 350. Does your test-statistic change? Does the critical value change?
A story describing a burger taste test among non-vegetarians was read by 352 high school students. To investigate the effect of the type of burger (veggie or meat) on subject's opinion of whether or not the burger tasted good, each burger had labels of veggie burger, beef burger, or a burger with no label. Each person was asked whether the burger tasted was good or not. Data are given in the accompanying table. Is there evidence that the proportion who believe that the burger tasted good for the three different labels differ? Test the relevant hypotheses using ? = 0.01. (Round your answer to two decimal places.) Taste Response Label Veggie Beef No Label Good 80 105 91 Bad 47 12 17 ?2 = P-value interval p < 0.001 0.001 ≤ p < 0.01 0.01 ≤ p < 0.05 0.05 ≤ p < 0.10 p ≥ 0.10 The data the conclusion that the proportion who believe a burger tasted good is not the same for the three labels.You may need to use the appropriate table in Appendix A to answer…
