of 8.2 hours. A. Using the sample data‚ construct a 99% confidence interval for the population mean. The confidence interval is as follows: 68.6- 2.58*8.2/ã50‚ 686+ 2.58*8.2/ã50 CI(65.6-71.5) B. Does the 99% confidence interval include the value suggested by the NCAA? Interpret the result. The result is interpreted by the result because 70 is inside the interval. C. Suppose you decide to switch from a 99% to a 95% confidence interval. Without performing any calculations‚ will the

provides a more accurate way of expressing data rather than mere observation. This experiment used the different statistical concepts such as the Q test‚ mean‚ standard deviation‚ relative standard deviation‚ range‚ relative range‚ and confidence limits or confidence intervals. The results generated from these tests are used as a basis to check whether the values obtained from weighing 10‚ 25 centavo coins using an analytical balance and which were grouped into two data sets‚ are acceptable or not
