Answer:
The <em>p</em>-value is 0.809.
Step-by-step explanation:
In this case we need to perform a significance test for the standard deviation.
The hypothesis is defined as follows:
<em>H</em>₀: <em>σ</em>₀ = 4 vs. <em>Hₐ</em>: <em>σ</em>₀ ≤ 4
The information provided is:
<em>n</em> = 9
<em>s</em> = 3
Compute the Chi-square test statistic as follows:


The test statistic value is 4.5.
The degrees of freedom is:
df = n - 1
= 9 - 1
= 8
Compute the <em>p</em>-value as follows:

*Use a Chi-square table.
Thus, the <em>p</em>-value is 0.809.
Answer:
800
Step-by-step explanation:
The Answer Is 8,000,000 Because
8×2 16 so 8,000,000 × 2=16,000,000
Answer:
Step-by-step explanation:
x = 3
y = 5
2x^2 + 3y^2 = 2 × 3^2 + 3 × 5^2
= 2 × 9 + 3 × 25
= 18 + 75
= 93
