Question 11 3 pts Use a 0.05 significance level to test the claim that weights of babies born to mothers given placebos vary more than weights of babies born to mothers given zinc supplements. Use the following statistics: Placebo group (1): n= 16,7 = 3,088 g, s = 728 g Treatment group (2): n-16, X = 3,214 g, s = 669 g A What is the null hypothesis? i. Ho: 01 02 ii. Ho: 01 202 iii.

A medical researcher wants to determine whether a drug changes the body’s temperature. Seven test subjects are randomly selected, and the body temperature (in degrees Fahrenheit) of each is measured. The subjects are then given the drug and after 20 minutes, the body temperature of each is measured again. The results are listed below. Use significance level α = 0.05, and we assume that the body temperatures are normally distributed. Show your work space provided below: t-Test: Paired Two Sample...

You obtain 169 successes in a sample of size n2=216 from the second population. For this test, you should NOT use the continuity correction, and you should use the normal distribution as an approximation for the binomial distribution. What is the z-score of the...

Question 1 (6 points) Two college instructors are interested in whether or not there is any variation in the way they grade math exams. They each grade the same set of 10 exams. The first instructor's grades have a variance of 59.2. The second instructor's grades have a variance of 72.5. Test the claim that the first instructor's variance is smaller. (In most colleges, it is desirable for the variances of exam grades to be...
