Astudy was conducted to identify the relationship between the hours of practice put in by the university at buffalo football team and the success they had in games won. the pearson's correlation coefficient was found to be .78. what type of relationship does this represent- positive or direct/negative or inverse? what is the strength of this relationship- weak, moderate, or strong?
a. direct, strong
b. direct, moderate
c. inverse, strong
d. inverse moderate.

A. Direct, strong

Step-by-step explanation:

If the Pearson's correlation coefficient is positive the relationship coefficient is direct. If it is negative, it is inverse.

If is considerate to be strong if it is larger than 0.7

In this problem, we have that:

The Pearson's correlation coefficient was found to be .78. It is positive, and larger than 0.7. So the correct answer is:

A. Direct, strong

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

a)(x-2)^2+(y-1)^2=9
