USAGE OF DATA ANALYSIS IN VARIOUS FIELDS

How data analysis as a booming industry is used in various fields viz., IT, Advertisement, Politics, etc.,

ONE SAMPLE T TEST

1) A researcher is interested in whether children from a small town are different at puzzle solving than the average child from the state in which the town is located. The average for the state is 64 minutes. A random sample of 30 10-year-olds from the small town wastested. The following data are the number of minutes it took each child to solve a series of abstract puzzles. Time to solve puzzles (minutes): 27 61 46 61 73 81 63 25 72 64 42 39 22 37 46 33 72 67 79 32 78 37 46 30 4 485 37 85 75 78 2) heck to make sure you input your data correctly. 3) a) What is the null hypothesis (words and symbols)? 4) b) What is the alternative hypothesis (words and symbols)? 5) c) Using SPSS, calculate the appropriate test to investigate the hypothesis presented 6) here. Print out the box for “One Sample Statistics” and “One Sample Test.” 7) NOTE: Remember to use the appropriate test value in SPSS. 8) d) What is the mean time to solve puzzles for this sample of 10-year-olds from this 9) small town? 10) e) What is the standard deviation of their time? 11) f) What is the standard error of this sample? 12) g) What are the results of the statistical test? Write them up in APA format. 13) h) What error did you possibly make (Type I or Type II)? Explain what that would 14) be for this example. 15) i) Using the mean and standard deviation from SPSS, construct a 95% confidence 16) interval, by hand, for the population mean puzzle solving time of all 10-year-olds 17) from this town. 18) j) Explain how you determine significance using the confidence interval. 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) Using SPSS, calculate 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 are the results of the statistical test? Write them up in APA format. e) What error did you possibly make (Type I or Type II)? Explain what that would be for this example. f) Using the mean and standard deviation from SPSS, construct a 95% confidence interval, by hand, for the population mean puzzle solving time of all 10-year-oldsfrom this town.
