1) A researcher is interested in whether students from NYU text more or less often than the national average. The researcher believes that the national average number of texts sent per day for smaitphone owners aged 18 to 24 is 67. A random sample of 40 NYU students was selected and the number of texts per day determined. The following data are the number of texts per day for the NYU students: Number of texts: 74.00 69.00 65.00 71 .00 67.00 73.00 72.00 70.00 77.00 63.00 72.00 65.00 69.00 53.00 32.00 55.00 73.00 74.00 63.00 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 SPS S. d) What is the mean number of texts of NYU students? e) What is the standard deviation of the number of texts? f) What is the stande error of this sample? 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 1])? 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 texts by NYU students. j) Explain how you determine signicance using the confidence interval
