1) A researcher is running an experiment on the effectiveness of three different energy drinks. She randomly selects 60 individuals from the population and evenly splits them into three groups, each of which consumes a different energy drink. a. The null hypothesis for this test is that at least one of the three groups will be different. True or False? The statistical results of the test are as follows: F(2, 47) = 6.24, p < .05. b. In the above...

Suppose two drugs are tested for effectiveness. 10 patients consume drug 1 and measurements are taken. A month later, another set of 10 patients consume drug 2, and measurements are recorded. You need to conclude if there is a difference in average response between the two drugs based on the measurements in the table below. Now, choose the correct test. Observation Drug 1 Drug 2 1 0.7 1.9 2 -1.6 0.8 3 -0.2 1.1 4 -1.2 0.1 5 -0.1 -0.1...

11 . Choosing the appropriate test statistic You are interested in the difference between two population means. Both populations are normally distributed, and the population variances σ212 and σ222 are known. You use an independent samples experiment to provide the data for your study. What is the appropriate test statistic? F = √[2/n1 + 2/n2] F = s1/s2 z = (x̄1 – x̄2) / √[σ2/n1 + σ2/n2] z = (p̂1 – p̂2) / √[p̂(1 – p̂)(1/n1 + 1/n2)] Suppose instead...
