Complete Parts A, B, and C below.

Part A

Some questions in Part A require that you access data from Statistics for People Who (Think They) Hate Statistics. This data is available on the student website under the Student Text Resources link.

1. Using the data in the file named Ch. 11 Data Set 2, test the research hypothesis at the .05 level of significance that boys raise their hands in class more often than girls. Do this practice problem by hand using a calculator. What is your conclusion regarding the research hypothesis? Remember to first decide whether this is a one- or two-tailed test.

The conclusion reached is that this is a two tailed test showing there is no difference between the levels of significance in boys or girls raising their hands.

2. Practice the following problems by hand just to see if you can get the numbers right. Using the following information, calculate the t test statistic.

a. [pic] Find the pooled S2 = 2.45 (9 / 18) + 3.16 (9 / 18) = 2.45 Variance for 1 = 2.45 / 10 = 0.245 Variance for 2 = 0.245 Pop Variance = 0.245 + 0.245 = 0.49 Sqrt 0.49 = 0.7 T = (62 – 60) / 0.7 = 2.86

b. [pic] Find the pooled S2 = 2.06 (21 / 46) + 2.59 (25 / 48) = 2.35 Variance for 1 = 2.35 / 22 = 0.107 Variance for 2 = 2.35 / 26 = 0.0903 Pop Variance = 0.107 + 0.0903 = 0.197 Sqrt 0.197 = 0.444 T = (158 – 157.4) / 0.444 = 1.35

c. [pic] Find the pooled S2 = 2.45 (16 / 32) + 2.35 (16 / 32) = 2.40 Variance for 1 = 2.45 / 17 = 0.144 Variance for 2 = 2.35 / 17 = 0.138 Pop Variance = 0.144 + 0.138 = 0.282 Sqrt 0.282 = 0.531 T = (200 - 198) / 0.531 = 3.77…...

List the five steps of hypothesis testing, and explain the procedure and logic of each. 1. Restate the question as a research hypothesis and a null hypothesis about the populations. a. This is the basic guidline by which the procedure will commence 2. Determine the characteristics of the comparison distribution a. One must choose which one is most applicable in the given situation 3. Determine the cutoff sample score on the comparison distribution at which the null hypothesis should be rejected. a. Here one can reject the null hypothesis if the cutoff score is higher than that of the sample one 4. Determine your sample’s score on the comparison distribution a. Once you compute your test one can observe if it is within the rejection range 5. Decide whether to reject the null hypothesis a. Once you have observed the rusults one can decide the final outcome 14. Based on the information given for the following studies, decide whether to reject the null hypothesis. Assume that all populations are normally distributed. For each, give: A 1.645 Z score cutoff Z = 2 reject B 1.96 Z score cutoff Z = 2 reject C 2.3263 Z score cutoff Z = 2 fail to reject D 2.576 Z score cutoff Z = 2 fail to reject |Study |µ ...
