The average final exam score for the statistics course is 78%. A professor wants to see if the average final exam score for students who are given colored pens on the first day of class is higher. The final exam scores for the 13 randomly selected students who were given the colored pens are shown below. Assume that the distribution of the population is normal. 90, 84, 93, 77, 95, 79, 82, 70, 85, 70, 83, 100, 90 What can be concluded at the the a = 0.05 level of significance level of significance?
Test the claim that the proportion of men who own cats is smaller than 90% at the .01 significance level. The test is based on a sample of 25 people, in which 84% of the sample owned cats. The null and alternative hypothesis would be: Ho:p = 0.9 H1:p < 0.9 The test is left tailed. What is the test statistic and critical value? (to 2 decimal places)
Compute test statistic (Independent t-score) Pooled variance S2p: Estimated standard error S(M1-M2) : Computed Independent t statistic: 2. Make a decision about the null hypothesis and state a conclusion. Decision: Are you going to reject the null or fail to reject the null Conclusion: ex. The independent variable did or did not have a significant effect Remember: if you reject, there was significance When people learn a new task, their performance usually improves when they are tested the next day, but only if they get 6 hours sleep (Sticckgold, et al., 2000). The following data demonstrate this phenomenon. The participants learned a visual discrimination task on one day. Half of the participants were allowed to have at least 6 hours of sleep and the other half were kept awake all night. 6 hours sleep No sleep…
Select the appropriate null and alternative hypothesis for the following research question: People who see therapists have lower depression scores than people who do not see therapists? xbar1 = the average depression score for people who see a therapist xbar2 = the average depression score for people who do not see a therapist O Null Hypothesis: People who see a therapist have depression scores lower than or equal to people who do not see a therapist i.e. xbar1 xbar2 O Null Hypothesis: People who see a therapist have depression scores higher than or equal to people who do not see a therapist i.e. xbar1 >= xbar2 Alternative Hypothesis: People who see a therapist have depression scores lower than people who do not see a therapist i.e. xbar1 < xbar2
