Answer:
a. should not be rejected
Step-by-step explanation:
H0 : σ² = 0.003
H1 : σ² > 0.003
We obtain the test statistic :
χ² = [(n - 1) * s²] ÷ σ²
s = sample standard deviation = 0.06
n = sample size = 26
σ² = 0.003
χ² = [(26 - 1) * 0.06²] ÷ 0.003
χ² = (25 * 0.06²) / 0.003
χ² = 30
Using the Pvalue from χ² calculator :
Pvalue = 0.2242
Using α = 0.05
Pvalue > α; we fail to reject the Null
Answer:
this is how you answer it
Simplify the square root of 54x^9y^7 or √(54x^9y^7)
54x^9y^7 = (3x^4y^3)^2 (6xy)
Now square root of (3x^4y^3)^2 = 3x^4y^3
So the final answer is 3x^4y^3 √(6xy)
