1. 2. 3. Assuming that other factors are held constant, which of the following would tend to increase the likelihood of rejecting the null hypothesis? Decrease the sample size Increase the sample mean difference Increase the sample variance None of the other 3 options would increase the likelihood Which of the following is the correct null hypothesis for a repeated-measures t test? MD 0 M1 M2 One sample of n=8 scores has a variance of s 6 and a second...
The null hypothesis for the independent-measures t-test states _____ A) M1 - M2 = 0 B) μ1 - μ2 ≠ 0 C) μ1 - μ2 = 0 D) M1 - M2 ≠ 0
Consider the following data from a repeated-measures design. You want to use a repeated-measures t test to test the null hypothesis H_0: mu_D = 0 (the null hypothesis states that the mean difference for the general population is zero). The data consist of five observations, each with two measurements, A and B, taken before and after a treatment. Assume the population of the differences in these measurements are normally distributed. Complete the following table by calculating the differences and the...
5. A step-by-step hypothesis test for a repeated-measures designConsider the following data from a repeated-measures design. You want to use a repeated-measures t test to test the null hypothesis H0: μD=0 (the null hypothesis states that the mean difference for the general population is zero). The data consist of five observations, each with two measurements, A and B, taken before and after a . treatment. Assume the population of the differences in these measurements are normally distributed.Complete the following table...

A researcher obtains t = 2.25 for a repeated-measures study using a sample of n = 10 participants. Based on this t value, what is the correct decision for a two-tailed test? Reject the null hypothesis with a -.05 Reject the null hypothesis with a -01 Fail to reject the null hypothesis with a - .05 Cannot determine without additional information
5. A step-by-step hypothesis test for a repeated-measures design Aa Aa E Consider the following data from a repeated-measures design. You want to use a repeated-measures t test to test the null hypothesis Ho: Wp = 0 (the null hypothesis states that the mean difference for the general population is zero). The data consist of five observations, each with two measurements, A and B, taken before and after a treatment. Assume the population of the differences in these measurements are...
The null hypothesis in an independent-samples t-test would be stated as which of the following: (A) The mean of the sample is equal to the mean of the population. (B) The mean of sample 1 is equal to the mean of sample 2. (C) The mean of sample 1 is not equal to the mean of sample 2. (D) The mean of the sample is not equal to the mean of the population
describe the data that are collected for a repeated-measures t-test and the hypothesis that the test evaluates
