The events for which the null hypothesis is rejected are called the critical region. Statisticians will not nomally reject a null hypothesis unless the probability of an outcome occurring in the critical region is less than 0.05. This means that data would appear by chance in the critical region even when H0 is true less than 5% of the time. This is referred to as a 5% significance level. a. Write down the significance level of your test.

b. Find the significance level for a different choice of critical region. Would you prefer this one over the one chosen previously? Justify your answer.

c. Comment on the symmetry of your critical regions and discuss whether they have to be symmetrical.

Like many students at university, you may be unhappy about the results you attain in exams. you may feel that even with all you are doing there must be something more -- or different-- you could be doing to get better grades. we have all at some time or other heard of that student who only studies a couple of hours for final exams and scores a's every time. we stand in awe of those who seem to breeze through without undue effort and seem to need very little in the way of studying to nail an exam. the reasons for success, in what i think are the vast majority of cases, are less esoteric than many students think: successful students consistently apply a series of productive strategies with view to attaining clearly identified learning and grade goals throughout the academic term.
