Assume that a new treatment for helping alcoholics isn't any better than an old treatment. A researcher, who doesn't know this, designs a study to compare the effectiveness of the two treatments. Based on the results of the study the researcher rejects the Null Hypothesis. What outcome has occurred?

scientific validation

type I error

type II error

A researcher conducted a single-sample null hypothesis test with the z-statistic. The researcher reports that z = +1.30. This z-statistic was calculated from sample data that was drawn from a normal population. The researcher sets α = .05 and uses a two-tailed test. On the basis of his data, the researcher decides to fail to reject the null hypothesis. Did the researcher make the correct decision or did he make an error? If he made an error, what type of...

1.) Choose the true statement. a.) If a null hypothesis is rejected for a test statistic at the α=0.05 level, then at the α=0.01 level it would never reject. b.) If a null hypothesis is rejected for a test statistic at the α=0.05 level, then at the α=0.01 level it would always reject. c.) If a null hypothesis is rejected for a test statistic at the α=0.05 level, then at the α=0.01 level it may or may not reject. 2.)...

1. After summarizing data collected to test a null hypothesis (e.g., observing z as a test statistic), a researcher fails to reject the null hypothesis (p > .05). The researcher then concludes that there is no treatment effect (treatment does not affect variation on the DV). Is this a correct conclusion? a. yes, it is correct b. no, it is incorrect; a decision to fail to reject the null hypothesis results in ignorance about a treatment effect 35. Consider z...
