A manager is considering placing an ad campaign on an emerging social media platform (e.g., Snap). To understand the demographics of usage for this platform, the manager takes a random sample of potential users and asks them if they participate in this social media platform. The results are shown below: Part of Social Media Platform Not part of social media platform Age < 30 75 33 Age >= 30 28 28 Is there a statistically significant difference in the proportions of participants in the platform for the two age groups “Age < 30” and “Age >= 30”? Use a 5% level of significance. (Hint: Please read the column headers carefully before launching into your test). Group of answer choices z = 2.44 > z-crit = 1.96, so there is a significant difference. z = 1.96 < z-crit = 2.35, so there is NO significant difference. z = 2.49 < z-crit = 2.58, so there is NO significant difference. z = 2.44 > z-crit = 1.65, so there is a significant difference.

Question

A manager is considering placing an ad campaign on an emerging social media platform (e.g., Snap). To understand the demographics of usage for this platform, the manager takes a random sample of potential users and asks them if they participate in this social media platform. The results are shown below: Part of Social Media Platform Not part of social media platform Age < 30 75 33 Age >= 30 28 28 Is there a statistically significant difference in the proportions of participants in the platform for the two age groups “Age < 30” and “Age >= 30”? Use a 5% level of significance. (Hint: Please read the column headers carefully before launching into your test). Group of answer choices z = 2.44 > z-crit = 1.96, so there is a significant difference. z = 1.96 < z-crit = 2.35, so there is NO significant difference. z = 2.49 < z-crit = 2.58, so there is NO significant difference. z = 2.44 > z-crit = 1.65, so there is a significant difference.
