What is the relationship between power and N, size of real effect, and alpha level? How does power fit into the hypothesis testing process? Compare the z test and t test for single samples. What are the advantages and disadvantages of each? Discuss. In presenting the t test for single samples, it was necessary to introduce the concept of degrees of freedom. However, no such discussion was needed in presenting the z test for single samples. What is the explanation of this difference?

A study of color in tiger beetles is conducted to support the contention that the proportion of black beetles may vary from locality to locality (alpha=0.05). A sample of 500 beetles caught in one season near Providence, Rhode Island, yielded 95 black beetles. A catch of 112 beetles from Aqueduct, New York, contained 17 black individuals. 1. What is null and alternative hypothesis? 2. What proportions did you observe in the two localities? 3. What is the null standard error for the difference? 4. Calculate the appropriate test statistic. 5. What p-value do you associate with that statistic? 6. What do you conclude about the proportion of black beetles in the two locations?
Morgan City Fire Chief Sidney Pyro is concerned about the low efficiency scores that his firefighters receive at the state testing institute. Chief Pyro believes that these scores result because some firefighters are not in good physical condition. Pyro orders 75 randomly selected firefighters to participate in an hour of exercise per day. Another 200 firefighters have no required exercise. After 60 days, all firefighters are tested again by the state. Chief Pyro collects the data and performs a two-sample independent t-test by using SPSS to examine if there is a statistically significant difference between the treatment and control groups; the SPSS results are shown in the table below. Group Statistics Groups N Mean Std. Deviation Std. Error Mean Test Scores Treatment 75 74.5 31.4 3.6 Control 200 70.6 26.3 1.9 a.

Answer true or false to the following statements and explain your answers.a. If the blocking factor in a randomized block design is a random effect factor, the F-test for the effect of the treatment factor is still valid when there is interaction between the treatment and blocking factors.b. The F-test for the effect of the blocking factor in a randomized block ANOVA is still valid when there is interaction between the treatment and blocking factors.c. The presence of interaction between the treatment factor and blocking factor in a randomized block design is easy to assess from interaction plots.
What statistical test would you use for each of the following scenarios? What would you set your alpha-level at? Sarah wants to know how gender impacts heart rate recovery after a maximal exercise test. In order to test this, she has both male and female athletes come into her lab and she measures both resting heart rate before the exercise test and heart rate immediately, 10 minutes, 20 minutes and 30 minutes following the exercise test. In order for her to determine whether heart rate differs pre-post exercise between males and females what statistical test might she use? Why?
Under what circumstances can you use a z-test instead of a t-test to compare a sample against a population?
Give the null and alternative hypothesis of The following are the laboratory results in hemoglobin of 10 male (X1) and 10 female(X2) patients. Test the null hypothesis that there is no significant difference between the hemoglobin of male and female patients. Use the t -test at 0.05 level of significance. As part of the National Health Survey conducted by the Department of Health and Human Services, perceptions on the attitude and practices of vaccine were obtained for females aged 18-30 before and after intervention. Listed below are sample mean results. Is there sufficient evidence to support the claim that there is a difference in the attitude and practice between before and after intervention? Use a 0.05 significance level. A researcher determines the BMI index of geriatrics from Tondo. Using 0.05 level of significance, is the BMI index of geriatrics are within the accepted norm (21)?
