Shown below is the confidence interval (CI) for the difference, , - H2, between two population means. Interpret the confidence interval. 90% Cl is from 15 to 20 Choose the correct answer below. O A. It can be said, with 90% confidence, that the value of u, is somewhere between 15 and 20 greater than the value of uz. Note that this means the difference between the two means is greater than zero. O B. It can be said, with 90% confidence, that there is no significant difference between the value of u, and the value of µz. Note that this means the difference between the two means may be zero. O c. The true value of u, - 2 lies somewhere between 15 and 20. Note that this means the difference between the two means is greater than zero. O D. It can be said, with 90% confidence, that the value of l, is somewhere between 15 and 20 less than the value of lz. Note that this means the difference between the two means is less than zero.
