Review of Independent t-test
Base your answers on the following problem and data. A student researcher wants to test
the hypothesis that students who are made to feel anxious by a critical teacher cannot
learn math concepts as well as students who are assigned to a supportive teacher. For the
student's 301 project, the student recruits 14 participants and randomly assigns the
participants to learn new math concepts from either a critical (n=7) or supportive
teacher (n=7). All other variables are kept the same; in fact, a single person performs
the roles of both the supportive and critical teacher, but just modifies her behavior
accordingly. Each group of participants then takes a test after the math lesson and their
scores on the test are measured. Here is the resulting data:

How do the Type I and Type II error rates of one-tailed and two-tailed tests differ?
A paint company has large outlet stores in two cities. Ten samples of the weekly sales (in tons) for the two cities are as follows. City A: n = 10, X10 = 148.5, S1 = = 4.3. City B: n = 10, Y 10 = 144.2, S2 = 3.8. At a = 0.05 level of significance, test if the weekly sales are different. The following ¨answers" have been proposed. (a) The null hypothesis is that the weekly sales are the same and the alternative is that the they are not the same. By using an F test, we reject the null hypothesis. (b) The null hypothesis is that the weekly sales are the same and the alternative is that the they are not the same. By using an F test, we do not reject the null hypothesis.

The manager of a political party wants to find out the association between the campaign spending (Large, medium and small) and the vote obtained (Majority, Average and minority). Use Chi-squared hypothesis test for association to test that there is an association between the variable in campaign spending and the variable in vote obtained with five percent level of significance. The manager uses MS excel to calculate the Chi-squared stat value and the result is 8.874. Critical value: At 1% = 13.277 :At 5% = 9.488 :At 10% = 7.779 1. State the decision rule 2.
