POBLEM SOLVING : 1.The researchers were interested in the differences in heart rate between men and women while waiting for an interview. Use a Mann-Whitney U test to test if heart rate differs between men and women at the 95% level. The following data is provided: What is the U value based on the given information?

The Mann-Whitney U test is used to compare differences between two independent groups when the variable of interest is on the _______ scale.Answ

Which type of experimental design can be analysed using a Mann-Whitney U test?Question 3Answera.A study in which doctors' happiness was measured on a scale along with the number of hours that they worked in a week.b.A study in which the frequency of participants was recorded for choosing a final year option in cognitive psychology, social psychology, or neuroscience for young versus mature students.c.An independent-sample design in which the number of correct responses on a statistics exam were recorded for two groups of participants: one group received their teaching online and the other group on campus.d.A repeated-measures design in which reaction times on a task were recorded before and after having caffeine.
