The next step in solving this problem is to calculate the mean (x bar), the median (mu), and the standard deviation (s) of the sample. All of those calculations were easily computed in excel. The mean was computed by entering: =average, the median by: …show more content…
In this case the null hypothesis is there ARE sixteen ounces in each bottle. The alternate hypothesis is that there are NOT sixteen ounces per bottle. In order to understand the outcome of this hypothesis, we will analyze the data set and our projections in the previous questions to answer them.
Analyzing the data from above, we have a mean of 14.9 and a standard deviation of 0.55. When we add one standard deviation to the mean, we still do not get to sixteen (16) ounces, but
