Standard deviation =square root of ∑ (X-X) 2 n-1 182.3+170.18+177.8+156.21+175.26= 861.75/5= 172.35 861.75-172.35= (689.40) 2 = 475272.36/(5-1)=118818.09 square root of 118818.09= 344.70 On Excel 6.) Standard Error of mean for shuttle run: SE=s/square root of n =1.47/square root of 68= .178 Confidence Interval for Standard Error of the Mean: 68%: mean + and – Standard Error : 11.17 + .178 = 11.38 : 11.17 - .178 = 10.99

The mean of the population for the shuttle run is 11.17. The confidence interval is that 68% of people fall within 10.99 to 11.38 seconds. Stats 2 1.) On Excel 2.) z-score and T-score for standing long jump of 80 inches: 80 inches x 2.54 cm= 203.2 cm z-score = X-X/s = 203.2-176.51/ 34.7= .769060874 T-score= (z-score x 10) + 50 = (.769060874 x 10) +50= 57.7=58 3.) Z-score and T-score for shuttle run of 10 seconds: z-score = 11.17 – 10/ 1.47 = .796 T-score = (.796 x 10) +50 = 57.96=58 4.) z-score and T-score for my shuttle run: z-score = 11.17 – 10.7 / 1.47 = .3197
