A researcher wants to test the difference in the amount of active cultures of 2 types of yogurt. This is the data from the study where 5 random samples of each type were measured. Calculate the mean, standard error of the mean and 95% confidence interval for each type of yogurt. What would you conclude about the difference between the types of yogurt from this data?
