Answer:
H0 : μN ≤ μD
H1 : μN > μD
Right tailed
Test statistic = 1.33
Pvalue = 0.097
Fail to reject the Null
Step-by-step explanation:
H0 : μN ≤ μD
H1 : μN > μD
The test is right tailed ; culled from the direction of the greater than sign ">"
Night students :
n1 =30 x1= 3.34 s1 = 0.02
Day students:
n2 = 30 x2 = 3.32 s2 = 0.08
The test statistic :
(x1 - x2) / √(s1²/n1) + (s2²/n2)
T= (3.34 - 3.32) / √(0.02²/30) + (0.08²/30)
T = 0.02 / 0.0150554
Test statistic = 1.328
Using the conservative approach ;
df = Smaller of n1 - 1 or n2 - 1
df = 30 - 1 = 29
Pvalue(1.328, 29) = 0.097
At α = 0.10
Pvalue < α ; Hence, we reject H0 ; and conclude that there is significant evidence that GPA of night student is greater than GPA of day student
When you reflect a line segment, it would create a mirror-image of itself about the specified axis. Thus, if you reflect it over the x-axis, it will now be situated at the 4th quadrant, because it is what's opposite to the 1st quadrant with respect to the x-axis.
Triangle
Area = 1/2 b * h
Area = 1/2*15 * 9 = 1/2 * 135 = 67.5
Rectangle
Area = b * h
Area = 15 * 4
Area = 60
Trapezoid
Area = (1/2) * (b1 + b2)* h
Area = (1/2) * (15 + 18) * 4
Area = 1/2 * 33 * 4
Area = 66
Total Area
Total Area = 66 + 60 + 67.5 = 193.5 Answer
The answer i got was
-89/x-9x-10
$3/6 = .50 per orange
$2.40/3 = .80 per grapefruit
10(.50) + 11(.80) =
$5.00 + $8.80 = $13.80
