Here are the answers to these three questions:
1. The null hypothesis is l ¼ 3, and the research hypothesis is l 3 on this 5-point
scale (i.e. the ‘‘middle’’ of the scale is 3).
2. The null hypothesis is l ¼ 4, and the research hypothesis is l 4 on this 7-point
scale (i.e., the ‘‘middle’’ of the scale is 4).
3. The null hypothesis is l ¼ 5 : 5, and the research hypothesis is l 5 : 5 on this
10-point scale (i.e., the ‘‘middle’’ of the scale is 5.5 since there are 5 numbers
below 5.5 and 5 numbers above 5.5).
As another example, suppose Texas Parks and Wildlife uses a 4-point scale in
its post-hunting satisfaction survey. The results of this survey are used to
determine the number of licenses issued for wildlife management the following hunting
season. The scale is as follows:
1 = Not So Good
2 = Average
3 = Very Good
4 = Great
On this scale, the null hypothesis is: l ¼ 2 : 5 and the research hypothesis is:
l 2 : 5 ; because there are two numbers below 2.5, and two numbers above 2.5 on
that rating scale.
Now, let’s discuss the 7 STEPS of hypothesis testing for using the conﬁdence
