Researcher's want to investigate the relationship between subjects' test scores on a test of empathy and their gender, age in years, whether they were a parent or not, and their education level in years.
a) What test would you use?
b) What are the null and alternative hypothesis?
Homework Answers
Answer)
While testing association or relationship we use correlation test
A)
So we should use correlation test
B)
If correlation coefficient is 0 then there is no relationship between two variables and if correlation coefficient is not equal to 0 then there is relationship in between variable
So, null hypothesis is that population correlation coefficient is equal to 0
And alternate hypothesis Ha is that population correlation coefficient is not equal to 0
Ho :p = 0
Ha : p not equal to 0

. propose a between-subjects experimental design to test the relationship. The IV and DV are already identified for you. Please explain how you would investigate the relationship by including: (1) your hypothesis (.e., what do you expect to happen), (2) an operational definition for your dependent variable (i.e., how will you test the variable), (3) the population (who do you want to recruit and why), (4) the levels of the IV (how many, what they are, and why), and (5)...

Listed in the data table are 10 scores for a random sample of subjects with medium load levels in their blood. Also listed are statistics from a study done of IQ scores for a random sample of subjects with high lead levels. Assume that the two samples are independent simple random samples selected from normally distributed populations. Do not assume that the population standard deviations are equal. Complete parts (a) and (b) below. Use a 0.05 significance level for both...

37. Use the following information for questions 37-38: Suppose you conduct a hypothesis test to determine whether or not the average age difference between married couples is less than 5 years. You conduct this test at the 0.10 significance level and come to the conclusion that 0.01 < p-value < 0.02. What is the correct decision? a. Fail to Reject the Null Hypothesis b. Reject the Null Hypothesis c. Accept the Null Hypothesis d. Accept the Alternative Hypothesis

To test the relationship between gender and ratings of a promiscuous partner, a group of men and women was given a vignette describing a person of the opposite sex who was in a dating relationship with one, two, or three partners. Participants rated how positively they felt about the individual described in the vignette, with higher ratings indicating more positive feelings.
