Consider the following data drawn independently from normally distributed populations: (You may find it useful to reference the appropriate table: 2 table or t table) a. Construct the 95% condence interval for the difference between the population means. (Negative values should be indicated by a minus sign. Round all intermediate calculations to at least 4 decimal places and final answers to 2 decimal places.) c _u_ TABLE 2 Student's f Distribution Entries In this table provide the values of try that correspond to a given upper-tail area a and a specified number of degrees of freedom df. For example, for a = 0.05 and of = 10, PUT , 2 1.812) = 0.05.
