**Study on Bug Repellent Effectiveness**A new bug repellent was tested on 17 subjects over a 10-hour period. The percentage of skin surface protected from bites was recorded for each subject. The observed results were as follows:- Mean (\(\overline{x}\)): 92- Standard deviation (\(s\)): 12**Objective:**The repellent is deemed effective if it achieves a repellency rate of at least 90%. To test this, we use a hypothesis test with:- Null Hypothesis (\(H_0\)): \(\mu = 90\)- Alternative Hypothesis (\(H_1\)): \(\mu > 90\)**Significance Level:**- \(\alpha = 0.01\)**Tasks:**(a) **Degree of Freedom:** Calculate the degree of freedom needed for the test.(b) **Critical \(t\) Value:** Determine the critical \(t\) value for the given significance level and degree of freedom.(c) **Test Statistics:** Compute the test statistics to evaluate the effectiveness of the bug repellent.

To compare the effectiveness of competing fertilizers on increasing radish size, researchers randomly divided 20 radish seeds of the same type into two groups of 10 and planted them. To one of the groups, they applied Fertilizer A, and to the other, they applied Fertilizer B. Then the researchers measured the radii of the radishes grown from the seeds in the two groups. The mean radius of the Fertilizer A group was 0.52 inches smaller than the mean radius of the Fertilizer B group. The researchers wanted to determine if this difference was due to the type of fertilizer or simply due to more seeds that produced smaller radishes being randomly assigned to the Fertilizer A group. To test if a difference of the means (A - B) of -0.52 inches or less could be due to chance, the researchers used a computer simulation to shuffle and randomly reassign the radishes to the two fertilizer groups. The difference between the two group means was then calculated and plotted on a dot plot. They…

QUA For Numbers 11 to 15: To determine the efficacy and lethal dosage of cardiac relaxants, anesthetized guinea pigs are infused with a drug (A, B, C, or D) until death occurs. Each drug was randomly assigned to ten guinea pigs, and the total dosage required for death of each guinea pig was recorded (smaller lethal doses are considered more effective). The software output of the analysis are given below: ANOVA Assumption Checks ANOVA - total_dosage Homogeneity of Variances Test (Levene's) Sum of Squares Mean Square df1 df2 df 36 0.307 drug 265 88.49 9.87 <001 1.25 3 Residuals 323 36 8.97 Normality Test (Shapiro-Wilk) Statistic 0.979 0.670 11.

A psychologist would like to examine the effects of different testing methods on the final performance of college students. One group has regular quizzes, one group has three large exams, and the third group only has a final exam. At the end of the course, the psychologist interviews each student to get a measure of the student's overall knowledge of the material. Do these data indicate any significant differences among the three methods? Do the following computations: a. Compute and report the F Ratio at a a = .05 b. Compute and report the Tukey's HSD to determine exactly which methods are significantly different.

In the experiment, a group of college students was told that they were participating in a manual dexterity study. Half of the students were given a stack of money to count and the other half got a stack of blank pieces of paper. After the counting task, the participants were asked to dip their hands into bowls of very hot water (122°F) and rate how uncomfortable it was. The following data show ratings of pain similar to the results obtained in the study. A. State null and alternative hypotheses b. Report results of statistical test, i.e., significant or not? Use .05 2-tailed alpha level. (what error might you be making) c. Report Cohen’s d value and interpret
(6 to 9) The level of cretaine phosphokinase (CPK) in blood samples measures the amount of muscle damage for athletes. At Jock State University, the level of CPK was determined for each of 25 football players and 15 soccer players before and after practice. The two groups of athletes are trained independently. The data summary is as follows : For football players: n=25 Before Practice After Practice Difference (Before-After) Mean 254.73 225.6 29.13 Standard deviation 115.5 132.6 21.00 For soccer players: n=15 Before Practice After Practice Difference (Before-After) Mean 177.1 173.8 3.3 Standard deviation 60.7 64.4 6.88 Assume that all the data above are normal, use the information above to answer problem (7) Construct a 95% Confidence Interval for the difference in mean CPK values for football players BEFORE and AFTER exercises.
