I have tried 4 which was incorrect
For a comparison of two study guides for a mathematics course, 12 student volunteers were found. They were randomly assigned, 6 to study guide A, and 6 to study guide B. Following a two-day period of independent study, the students were examined on the material. The students received the following scores (out of 100): Study Guide A: 98 88 89 79 96 89 Study Guide B: 76 63 80 69 82 65 Use...

Samples of three different species of amphibian (frog, toad and salamander) were collected and dissected and the number of parasites found within each was counted and recorded. The researchers are interested in determining whether the distribution of parasites across species is different. The number of parasites within each sample was counted and recorded.

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...
