Consider the example from the previous problem, in part (b). The sizes (in grams) of Latavia's 14 oranges are 124, 126, 129, 130, 134, 136, 139, 142, 146, 149, 152, 154, 155, and 157 g. a. Find the sample mean of Latavia's data. b. Make a boxplot or a histogram of Latavia's data with a bin size of 10. c. If even a small sample is graphed and has no major skew or outliers, it is generally reasonable to assume that the population “could reasonably be normal," and therefore that the sampling distribution of the mean is approximately normal. This is the "normal population" condition. Does this sample appear to satisfy this condition? d. Latavia reads online that medium-sized navel oranges have a mean mass of 131 g with a standard deviation of 18 g. She is interested to test if the Fresh Foods oranges match those parameters. State a null and alternative hypothesis for this situation using symbols. Note that Latavia is making two assumptions in her test. e. Calculate a test statistic: what…
