A survey was conducted to investigate trends of romantic relationships and online behaviors. Out of 250 adults in their 20s (20 to 29), 180 reported using social media to check on an ex (someone they used to date / be in a romantic relationship with). Out of 260 adults in their 40s (40 to 49), 156 reported using social media to check on an ex. You will perform a hypothesis test to see if the data provide evidence that there is a difference between the age groups in the proportions of people who checked on an ex. Let p1 represent the proportion of people in their 20s who used social media to check on an ex. p2 represents the proportion of people in their 40s who used social media to check on an ex. How can we write the null hypothesis? a. H0: p1 = p2 b. H0: p1 ≠ p2 c. H0: p1 > p2 d. H0: p1 < p2
