MADE OF SUGAR GUM BASE DEXTROSE, CORN SYRUP. LESS THAN 2% OF NATUR ME SOY LECITHIN, ACESULFAME K, BH 6 (2pts total) Using the final exam scores in Question #5 for ALL 10 students of your dataset above, a). Construct the 96% confidence interval to estimate the parameter. Home work score Critical value for 96% is 2,054 mean = 76.1 lower limit - 76.1 - 2.054 (12.35988 JID 180) = 68.07 SD = 12. 35988 upper limit = 76.1 + 2.054 ( 12,35988 ) = 84.13 Final Exam Score mean = 73. 8 lower limit = 73:8- 2.054 ( 15:54718 ) = 63.7 SD = 15, 54778 upper limit = 73,8+ 2. 054 (- 15. 541 12 1 = 83.9 N lo b). Without doing any calculations, would you expect the confidence interval from Part (a) to become narrower or wider if the sample size were 160? How much would it change the interval? Would it be more precise? Explain briefly by discussing what would happen to the standard error and margin of error
