Dаtа set оn the аcademic perfоrmance and sоcial media hours. 705 students from multiple countries particiated in a survey which collected data for the 2 categorical variables: Is social media affecting your academic performance? and What is your academic level?. Are these 2 variables independent or associated? Do a Chi-square test with contingency table to conclude. In Display options, click on Expected count (shown in paranthesis in output). Observing table Of the students surveyed, how many highschoolers responded "Yes, social media is affecting my academic performance"? [i] If the two variables studied are not associated, how many highschoolers do we expect to respond "Yes, social media is affecting my academic performance? [j] Do not round. The actual count is [k] the expected count. (more than / same as) Testing hypothesis Null Hypothesis : The variables Social media affecting academic performance and Academic level [a] associated. (are / are not) Alternate Hypothesis : The variables Social media affecting academic performance and Academic level [b] associated. (are / are not) What is the Chi square Value that is next to the p-value [e] Do not round. The p-value is [c] Do not round. The p-value is [f] than the level of significance. (more / less) We [g] claim that the variables Social media affecting academic perform and Academic level are associated. (can / cannot) Does sample data indiacte the variables Social media affecting academic performance and Academic level are independent. [h] (yes / no)
StаtCrunch Sаmple dаta оn Usage minutes fоr different Sоcial media platformsis given. Let all Instagram users be population 1 and all Facebook users be population 2. Work directly with data set (TStat, with data) to find the 95% confidence interval for difference in mean usage minutes. Questions In the sample data, the difference in the mean times students spend on Instagram and on Facebook is [c] minutes. Do not round. Type or copy paste as in StatCrunch output. Is this difference significant enough to claim the mean minutes students spend on Instagram is more than the mean time they spend on Facebook? We are 95% confident that difference (in minutes) in the mean times for the two social media platforms is between [i] min and [j] min. Do not round. Type or copy paste as in StatCrunch output. The range of values for the difference in mean usage minutes for the two social media platforms is [k] (Use positive / negative / both) Based on the 95% confident interval, we [e] (can / cannot) claim the mean number of minutes student spend on Instagram is [a] (more / less) than that of Facebook. Concluding for all students in the population, we can be 95% confident that the mean time students spend on Instagram is [f] minutes to [g] minutes more than that of Facebook. Round to whole number.
