statistics (correlation/regression). Multiple choice practice questions. please help in answering all. thank you

A college student wants to determine if degree of introversion/extroversion is associated with life satisfaction. She has a sample of 68 people take two surveys. Each survey has multiple questions measured on 1 (agree) to 7 (disagree) scales; a mean average is computed for each person's final score on each survey. The first survey yields a higher score the more extroverted a person is. The second survey yields a higher score the more satisfied a person is with their life. What statistic should you use to determine if scores on these two surveys are related to each other? two-way ANOVA correlation analysis goodness of fit chi-square test independence chi-square testIn calculating the Pearson correlation (r), the hypothesis implies null; the means are all equal to each other null; the relationship is not linear alternative; the two population means are not equal alternative; there is a relationship between the two variables
