Hello I am taking 1st year stats at university, and I have lab questions I am supposed to answer. I am VERY confused. My data set is: 53, 33, 25, 63,26, 64, 32, 21, 45, 64, 38 I calculated the mean:42.182 the sample variance:272.147 The range:43 The percentile rank of the data value 45: 59th The value corresponding to the 80th percentile:63 Q1:26 Q2:38 Q3:63 Outliers: none Standard deviation: 16.497 Now I am asked: according to the empirical rule, if the above data is normal find the range of values in which approximately 68% of the data will lie. I know the empirical rule applies only to bellcurved graphs... but this would not produce a bell curve correct? So would there be an answer? Then they ask: What is the actual percentage of the data that lie in your interval from above.? Any help is appreciated thanks!
