4. Mr. Smith bought 16 oranges and Ms. Green bought 16 oranges in different stores picking oranges randomly. The mean weight of Mr. Smith's oranges is x = 300 grams and the mean weight of Ms. Green's oranges is x = 250 grams. Both groups of oranges show equal standard deviation, i.e. s, = s, = 48 grams. Is the difference of the mean weights of the oranges is statistically significant with sampling error a = 5% (alpha). In the other words, can someone claim that the oranges of those stores have different average weight? 5. How to use Harvey balls in a comparative analysis? Provide an example. 6. What is the report outline, why is it needed, and how to develop it? Provide an example. 4. Mr. Smith bought 16 oranges and Ms. Green bought 16 oranges in different stores picking oranges randomly.
