A researcher was interested in the relationship between an average daily time spent on social media (i.e., X variable) and social anxiety (i.e., Y variable).

The data collected on a sample of n = 82  undergraduate students produced the following results:        SSx= 49, SSY= 36, SP = 11, MX = 8, MY = 15.

A. Is there a significant correlation between an average daily time spent on social media and social anxiety? Use 2-tailed test, p < .05 to answer this research question.

  • Formulate the null and alternative hypothesis.
  • Compute the Person correlation, r
  • Find the r critical for this study.
  • Make a decision about the null hypothesis.
  • Write the conclusion and report the Pearson's correlation outcome in the APA style format.

B. Find the regression equation for predicting social anxiety (Y variable) from the average daily time spent on social media (X variable).
