Step-by-step explanation:
(a)
H0 : μ = 12
H1 : μ > 12
This is a right tailed test ; the alternative hypothesis has a greater than sign, difference between sample and population mean value will be positive.
(b)
H0 : μ = 10
H1 : μ > 10
This is a right tailed test ; the alternative hypothesis has a greater than sign, difference between sample and population mean value will be positive.
(c)
H0 : μ = 100
H1 : μ < 100
This is a left tailed test ; the alternative hypothesis has a less than sign, difference between sample and population mean value will be negative.
(d)
H0 : μ = 12
H1 : μ > 12
This is a right tailed test ; the alternative hypothesis has a greater than sign, difference between sample and population mean value will be positive.
Answer:
54
Step-by-step explanation:
2x+2=3x-52
-2x -2x
2=x-52
+52 +52
54=x
The given points in the problem is (7/4, 0) and (8,-9)
Then write the equation in point-slope form.this would be m = (-9 - 0)/(8 - 7) = -9
Then form this in the format: y = mx + b
then solve for "b":
-9 = -9*8 + bb = 8
The equation in slope form is:y = -9x + 8
