Perform a a Pearson’s correlation in SPSS to determine whether the weight of an automobile (‘weight’: Vehicle Weight-lbs) is significantly correlated with its horsepower (‘hp’: horse power).  Use a two-tailed test with α = .01 The alternative hypothesis in symbols and null hypothesis in words is:

A correlation coefficient should be used when the independent and dependent variable are measured as categorical nominal ordinal continuous

A professor wanted to study whether there was an association between a person's age and their likelihood to use social media. He surveyed members of Gen Z, Millennials, and Gen X. Below you will find the data that was collected: YES, use social media NO, do not use social media H₂: a=0.05 DF=_ Gen Z 78 11 a. Perform a Chi-Square Test for Association to see if there is evidence to show there is an association between age and likelihood to use social media? Ho: Conclusion: b. Fill in the blanks using your table: X²= Circle one: Millennials 124 19 Number of Gen Z that use social media= Total number of Gen Z surveyed = Gen X 79 24 P-value= Fail to Reject H. OR Reject Ho c. Use your survey results from part b to find a one-sample 95% confidence interval. d. According to an October 2022 study, approximately 93% of Generation Z use social media platforms. Does your confidence interval support or refute this claim?

COVxy = 0.14   Sx * Sy = 0.22     Please calculate the correlation coefficient

My solution is incorrect

How would I solve this part of the question? I'm not sure what to input for the excel formula "Use the paired t-test function (=ttest(array1, array2, tails, type) to determine the if the two sets of measurements are correlated with each other."

What does am/n mean ?

A set of n=15 pairs of scores (x and y values) has Ssx =200, Ssy=60, and Sp=30.What is the Pearson correlation for these data?

True or False: A spearman correlation is a theoretical correction for a Pearson’s correlation that boosts the size of the correlation when variables are assessed as ordinal but are actually assumed to be continuous.

A researcher computes the correlation coefficient r= 0.4212 for an explanatory and response variable. What proportion of the changes in the response variables value is accounted for by the change in the explanatory variable's value? Give your answer to four decimal places.
