Bottling Company Case Study: Name: Institution: In statistics, mean is an average of numbers. In order to determine it in this case study, I added all the number of ounces and divide them by the total number of bottles. The sums of ounces are 446.1 while the number of bottles is 30. As such, the mean is 446.1 / 30 is which is 14.9. On the other hand, the median is the middle or center number or data once they are arranged in order. Consequently, the median is the middle number of ounces in the bottles. In this case, the given numbers are in order. There are 30 entries (even number). Hence, the mean of 2 center numbers (14.8 and 14.8) will provide the precise median number. 14.8 +14.8= 14.8 2 Standard deviation is the term used to measure the way or how numbers are spread out. In essence, it calculated just to show the extent to which far apart some data is in a given scenario. The symbol for standard deviation is sigma (?). According to (Quinn & Keough, 2002), standard deviation may be calculated by finding the difference between entry mean and the entry data. In this scenario, once variance is obtained, it is divided by 30-1 giving rise to a standard deviation of approximately 0.55 after rounding down to 2 decimal places. Confidence interval is a phrase in statistics which measures probability that some population parameter falls between 2 value sets. In sum, the confidence interval comes about as the possibility that a certain value falls between a lower ...
