Answer:
Step-by-step explanation:
For testing of significance of correlation coefficient denoted by r, we create hypotheses in three ways
They are one tailed, two tailed. One tailed can be stated as right tailed and also left tailed.
The null hypothesis would normally be as r=0
Verbally we can say this there is no association between the dependent and independent variable (linear)
Against this alternate hypothesis is created as
either r not equal to 0
or r>0 or r<0
If r not equal to 0, we say two tailed hypothesis test
If r>0 is alternate hypothesis, it is right tailed test
If r<0 is alternate hypothesis, then it is left tailed test.
285% is same as 285/100 which equal 2.85
Then 2.85 x 171 = 487.35
Answer: 487.35
The answer would be 2.79 inches.
a. The slope represents the problem by making a statistic of the aging and the heights.
b. the y-intercept represents the height in inches. hope that helped
