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:
Step-by-step explanation:
what are the options
Answer:In Heather's solution to the problem, she wrote and solved an equation.
Her work is:
Step 1: 1.08(x +9.01 +0.98 +5.01) = 21.87
Solving like terms
1.08(x+15}=21.87
dividing both side by 1.08
we get
x+15=21.87/1.08
x+15=20.25
subtracting both side by 13.9198
x=20.25-15
x=5.25
According to correction
;
<u>Option 1st</u>
<u>yes,it is correct</u>
