In answering the question(s),make sure to write down the following 7 steps.
Step 1: Establish null and alternate hypothesesState the null and alternative hypothesis (as a sentence andformula).
Step 2: Calculate the degrees of freedom
Step 3: Calculate t critical using critical t– table
Step 4: Calculate the Sum of Square deviation(SSD)
Step 5: Calculate t obtained
Step 6: Specify the critical value and the obtainedvalue on a t-distribution curve
Step 7: Decision and Conclusion Write a clearand concise conclusion.
A researcher is interested in whether gender predictsthe type of costume people would wear to an upcoming party. He asks6 guys and 6 girls: How likely would you be to wear a “CreepyClown” costume to the upcoming Halloween party? (1 = very unlikelyto 7 = very likely). The data are shown below.
Guys: 4 6 4 3 6 7
Girls: 2 5 4 1 2 3
1. Use alpha = .01 to see whether gender impactswillingness to wear a Creepy Clown costume. (Note: You need towrite down all the 7 steps.)
2. Use alpha = .01 to see whether guys are more willingthan girls to a Creepy Clown costume. (Note: You only need to writedown the steps that are different from part (1).)
3. Use alpha = .05 to see whether guys are more willingthan girls to a Creepy Clown costume. (Note: You only need to writedown the steps that are different from part (1).)
