Two groups of guinea pigs were injected, respectively, with 0.5 and 1.0 milligrams of a tranquilizer, and the following are the numbers of seconds it took them to fall asleep:
0.5 mg dose: 8.2 10.0 10.2 13.7 14.01.0 mg dose: 9.7 13.1 11.0 7.5 13.3
Use Wilcoxon rank-sum test to test at the .10 level of significance to test the claim that the difference in dosage have significant effect on the length of time it takes guinea pigs to fall asleep.
(a) Set up hypotheses. : :(b) Find the observed value. Utilize the table below if you like.(c) State the rejection region.(d) State your conclusion and the reason.(e) Interpret the conclusion in part (d).
Using the p- value approach, test the hypotheses at the 5% level of significance.
Determine the p-value for this test. Is there sufficient evidence to justify the rejection of H0 at the "alpha" level of 0.01? Please explain your answer.
Is it necessary to assume a normal distribution on the population to estimate the value of the mean spending per day? Explain.
A square yard of carpet is examined for surface defects. Currently, the process produces an average of 2.4 defects per square yard. What is the probability of finding 2 or more surface defects in the sample.
Using z-scores, a population with mean = 37 and standard deviation = 8 is standardized so that the new mean is mean = 50 and standard deviation = 10. How does an individual's z-score in the new distribution compare with his/her z-score in the orig..
