The researcher has decided to use an alpha level of 5% for their research. They have drawn the above bell curve to aid them in understanding their results. Using this information, complete the following questions:

Question 1 - If the research is using a two tail statistical test, Area A and Area E are known as what type of areas? (2 points)

Question 2 – If the research is using a two tail statistical test, what do Line B and Line D represent? Do not answer alpha level. (2 points)

Solution

Q1)

area A and area E are know as rejection area, because the area central of the curve is the acceptacion regio of Ho

then area A and area E are rejection area of Ho

Q2)

line B and line D represent the critical values, if the value of test statistical is greater than the critical value we will reject Ho , but if the value of test statisitcal is less than the critical value we fail to reject Ho
