Answer: 0.0108
Step-by-step explanation:
Given : 
Since the alternative hypotheses is right-tailed, so the test is a right-tailed test.
Sample size : n=30
The degree of freedom for t-distribution= 
The by using the normal t-distribution table , we have
The P-value corresponds to t-statistic vale 2.43 and degree of freedom 29 , is 0.01075997 i.e. approximately 0.0108
4. y=-2x-2
5. y=2x-1
6. y=2x-4
7. y=-x
8. y=0+1-1.5
Step-by-step explanation:
Equation of a straight line
y = mx + c, m is the slope, and c the intercept
points (3,7) x = 3, y = 7, c = 1
7 = m × 3 + 1
7 = 3m + 1
3m = 7 - 1
3m = 6
m = 6/3
m = 2
Answer:
No y
Step-by-step explanation:
Since
x=-1
is a vertical line, there is no y-intercept and the slope is undefined.
