If and only if, which mathematicians abbreviate as iff. no kidding, you could look it up:)
Step-by-step explanation:
At the end of driving, what is your straight line distance from your starting point? Round to the nearest tenth of a mile.
The slope is the change in Y divided by the change in X.
You would need to know the coordinates of 2 points ( X1,Y1) and (X2,Y2), then subtract : Y2 - Y1 divided by X2- X1.
The solution to the Questions are
- The alternate hypothesis demonstrates that there are two possible outcomes for the test.
- Decision rule: If z > 2.05 or z<-2.05, reject H0
- The two-tailed nature of the test is shown by the alternative hypothesis.
- The result of the test yields the following P-value: 0.0096
<h3>What is the alternate hypothesis?</h3>
(a)
The alternate hypothesis demonstrates that there are two possible outcomes for the test.
(b)
Here we have
(b)
Here the test is two-tailed. So for , the critical values of the z-test are -2.05 and 2.05.
Decision rule: If z > 2.05 or z<-2.05, reject H0
(c)
Test statistics will be
z=2.59
(d)
The two-tailed nature of the test is shown by the alternative hypothesis.
(e)
The result of the test yields the following P-value: 0.0096

Answer:
-2/f for the first one, and 1/f is the second one!
