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...

1-2. The sample of n = 30 people is selected and the sample correlation between two variables is r = 0.468. 1. What is the test statistic value for testing whether the true population correlation coefficient is equal to zero? (calculate t-test statistic) 2. What is the t- critical value for alpha= 0.01. and what you can conclude about population correlation ( is there significant correlation between two variables).

a. If the Pearson’s correlation of likeability and numbers of movements replicated is r = +.25 is there enough evidence to conclude that the greater the number to mirrored moves the greater the likelihood that you will like the person? Use α = .05, two-t
a. If the Pearson’s correlation of likeability and numbers of movements replicated is r = +.25 is there enough evidence to conclude that the greater the number to mirrored moves the greater the likelihood that you will like the person? Use α = .05, two-tailed test and show your work. Please calculate these answers using BOTH methods demonstrated in the lecture. Be sure to label each one with Easy Method or Long Method. (4 pts)

You wish to conduct a hypothesis test to determine if a bivariate data set has a significant correlation among the two variables. That is, you wish to test the claim that there is a correlation (Ha:ρ≠0Ha:ρ≠0). You have a data set with 69 subjects, in which two variables were collected for each subject. You will conduct the test at a significance level of α=0.05α=0.05. Find the critical value for this test (Pick the closest conservative value from the table). rc.v....
