Answer:
We can conclude that the result is significant and production differ in cost variance.
Step-by-step explanation:
Given :
n1 = 16
n2 = 16
s1² = 5.7
s2² = 2.8
α = 0.10
H0 : σ1² = σ2²
H1 : σ1² ≠ σ2²
The test statistic :
Ftest = s1² / s2² =
Ftest = 5.7 / 2.8
Ftest = 2.036
Using the Pvalue from Fratio calculator :
df numerator = 16 - 1 = 15
df denominator = 16 - 1 = 15
Pvalue(2.036, 15, 15) = 0.0898
Pvalue = 0.0898
Since the Pvalue is < α ; We can conclude that the result is significant and production differ in cost variance.
The area of a square given its diagonal (d) is computed as follows:
In this case, the diagonal is 10 units long, then the area is:
Answer:
75 minutes
Step-by-step explanation:
First cook 40 and 45 min dishes on separate burners. Then after 40 min put 35 min dish to be cooked on that burner. This will take 75 minutes time.
On second burner put firstly 15 min and then 10 min dish or vice versa as it doesn't matter. This second burner will take 70 minutes which is less then first one.
Answer:
80=X
95=X
55=X
30=X
you simply add the numbers you have together then subtract that from 180
Answer:
The answer is false.
Step-by-step explanation:
The factors in the polynomial are not divided, but however dividing involves division of a polynomial expression with another expression but not the individual factors.
