True or False?
To compute a t statistic, you must use the sample variance (or standard deviation) to compute the estimated standard error for the sample mean. True False The 95% confidence interval for the difference between two treatment means extends from-2.50 to +5.50. Based on this information, you can conclude that there is no significant difference between the treatments at the .05 level of significance True O False
