Use this for writing up your results in APA format. 1) A researcher is interested in whether students from NYU spend more or less time on social media than the national average. According to recent research, people spent an average of 132 minutes per day on social media. A random sample of 40 NYU students was selected and the number of minutes spent on social media per day was determined. The following are the data for the NYU students: Minutes on social media: 125 122 132 128 136 120 148 147 130 144 117 142 120 122 120 135 122 143 120 146 138 116 118 127 124 133 118 125 128 122 134 128 122 154 144 114 110 150 135 127 Check to make sure you input your data correctly. a) What is the null hypothesis (words and symbols)? b) What is the alternative hypothesis (words and symbols)? c) Only using SPSS, run the appropriate test to investigate the hypothesis presented here. Print out the box for "One Sample Statistics" and "One Sample Test." NOTE: Remember to use the appropriate "test value" in SPSS. d) What is the mean number of minutes spent on social media by NYU students? e) What is the standard deviation of the number of minutes spent on social media? f) What is the standard error of this sample? 2 g) Only using SPSS. what are the results of the statistical test? Write them up in APA format (even if they are not significant). h) What error did you possibly make (Type I or Type II)? Explain what that would be for this example. i) By hand, using the mean and standard deviation from SPSS, construct a 95% confidence interval for the population mean number of minutes spent on social media by NYU students. j) Explain how you determine significance using the confidence interval. 2) Over many years of testing, I have considered the population mean of the Quiz 1 grades for my statistics class to be u = 86. I was curious whether my students from 2018 were significantly different from all of my other students over several years.

Write them up in APA format (even if they are not significant). h) What error did you possibly make (Type I or Type II)? Explain what that would be for this example. i) By hand, using the mean and standard deviation from SPSS, construct a 99% confidence interval that estimates the population mean Quiz 1 grade from the sample semester's data. *#* j) Using the confidence interval, do we find significance? Even if the results are the same, explain why our results with the confidence interval might differ from those of the t-test (Hint: think about alpha). Note: Although technically you could do a z-test because you have a large sample, you must do a t-test because that is the only test SPSS provides. Use t for the confidence interval as well.

Test the hypothesis that your sample data from one year (2018) (using Assignment Undergrad Data) are significantly different from the population. Answer the same questions (a-j) as in question 2, but for Final Exam Grade. *#* When looking up to on the t-table for creating confidence intervals: if of are greater than 120, use 120. 2 PDF SPSS 2 Guidline.pdf Show all X Type here to search X w P SP..
