The following data are from an independent-measures experiment comparing two treatment conditions.                     Treatment 1          Treatment 2

                                                        4                    19

                                                       5                    11

                                                       12                    18

                                                   10                    10

                                               10                    12

                                                   7                    14

(a) Calculate the mean for Treatment 1 and Treatment 2

(b) What is the Pooled Sample variance?

© What is the estimated standard error?

(d) Do these data indicate a significant difference between the treatments at the .05 level of    significance?

(e) Compute r2 to measure the size of the treatment effect.

(f) . Write a sentence demonstrating how the outcome of the hypothesis test and the measure
