Dr. S. compared her experimental group to a control group using a t test and concluded that her t was significant at the 1% level.  If  Dr. S. replicates her study using a similar sample of participants, she is most likely:   to find that the experimental group is different from the control group; to find that the experimental group is similar to the control group; to find that the distribution of scores in the experimen­tal group resembles a                                        normal curve; however, the distribu­tion of scores in the control group does not                              resemble a normal curve;             d.         The experimental group scores were correlated with the control group scores

Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.
