Mean 23.1043 Sample Standard Deviation 1.3693 Confidence Level n Mean StDev pop stdev SE t Margin of Error Lower Limit Upper Limit Lower margin of error = 22.69 and u ... pper limit is 23.51 8. Suppose that the scores of bowlers in a particular league follow a normal distribution such that a standard deviation of the population is 12. Find the 95% confidence interval of the mean score for all bowlers in this league using the accompanying data set of 40 random scores. Round your answers to 2 decimal places using ascending order. Lower Limit = 90.78 Upper Limit = 98.22 Confidence Level n Mean StDev pop stdev 25.8 22.2 22.5 22.8 24.6 24 22.6 23.6 22.8 23.1 21.5 21.4 22.5 24.5 21.5 22.5 20.5 23 25.1 25.2 23.8 21.8 24.1 0.900 32 23.1043 1.3693 no 0.242060 1.696 0.410534 22.693766 23.514834 0.950 40 94.5000 12.0000 [Show More]
