Paper For Above instruction

The core objective of this assignment is to develop and perform an inferential statistical hypothesis test based on a research question and associated variables. Specifically, the task involves crafting a clear research question, generating mock data for the independent and dependent variables, selecting an appropriate statistical test, and interpreting the results at a 95% confidence level. This process enables a deeper understanding of the application of inferential statistics in assessing relationships between variables within a business research context.

Research Question: Does the amount of time spent on social media influence the level of academic performance among college students? This question aims to understand whether a relationship exists between the hours devoted to social media and GPA scores.

Variables: The independent variable is "Hours spent on social media per day" (measured in hours), and the dependent variable is "Academic performance," operationalized through GPA scores (on a scale of 0.0 to 4.0).

Mock Data: For the purpose of hypothesis testing, assume a sample size of 30 college students. The data for the independent variable (social media hours) ranges from 1 to 6 hours per day, with a mean of 3.5 hours. The dependent variable (GPA) ranges from 2.0 to 4.0, with a mean GPA of 3.0. Corresponding data points show a negative correlation—higher social media usage tends to associate with lower GPA scores.

Statistical Tool Selection: Given the variables are continuous and presumed linearly related, a Pearson correlation coefficient test is appropriate to measure the strength and direction of the relationship. To test the significance of this relationship, a hypothesis test for the correlation coefficient is suitable.

Hypotheses:

- Null hypothesis (H₀): There is no correlation between hours on social media and GPA (ρ = 0).

- Alternative hypothesis (H₁): There is a correlation between hours on social media and GPA (ρ ≠ 0).

Results: Using the mock data, the calculated Pearson correlation coefficient (r) is approximately -0.65, indicating a moderate negative relationship. Conducting a hypothesis test at the 95% confidence level yields a t-value of about -3.77 with 28 degrees of freedom, which exceeds the critical t-value of approximately ±2.048. Therefore, we reject the null hypothesis.

Interpretation: The statistically significant negative correlation suggests that increased social media usage is associated with lower academic performance among college students. This finding underscores the importance of managing social media consumption to enhance academic success.
