Below are descriptions of some research studies. Each description contains sufficient information to determine the correct statistical test to use. Your task is 1) to determine which is the correct test, 2) to perform that test using our five-step hypothesis testing procedure, and 3) to make a decision about the null hypothesis using the results of the test. Choose your tests from these options: single-sample i test dependent-measures / test independent-measures t test Please report your answers in the following...
