A set of anatomy test scores has a mean of 27 and a standard deviation of 4.2. Calculate the raw scores for each of the following z scores: –5.3, –2.1, 0, 1, and 3.1.
z=rawscore-mean/sd
for -5.3
-5.3=x-27/4.3
x=-5.3*4.3+27
x= 4.21
For
z=-2.1
-2.1=x-27/4.3
x=-2.1*4.3+27
x= 17.97
For z=0
x=0*4.3+27=27x=27
For z=1
x=1*4.3+27=31.3
For z=3.1
x=3.1*4.3+27=40.33
e raw scores for each of the following z scores: –5.3, –2.1, 0, 1, and 3.1. are
4.21,17.97,27,31.3,40.33
8. For the following research question, create one null hypothesis, one directional research hypothesis, and one nondirectional research hypothesis.
Null::There is no relationship between the quality of a marriage and the quality of the spouses’ relationships with their siblings
Directional:
quality of a marriage increases the quality of the spouses’ relationships with their siblings
Nondirectional:
There is a relationship between the quality of a marriage and the quality of the spouses’ relationships with their siblings.
