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:
Option a.
I and III
Step-by-step explanation:
Observing the graph
For n=400 coats
The cost is about $2,200
and
The revenue is less than $1,400
Substitute the value of n=400 in each equation to find the solution
I Cost 1.5(400)+1,600=$2,200 ----> is ok
II Cost 4.5(400)+1,600=$3,400 ----> is not ok ( is greater than $2,200)
III Revenue 3.25(400)=$1,300 ----> is ok ( is less than $1,400)
IV Revenue 5.75(400)=$2,300 ----> is not ok ( is greater than $1,400)
therefore
The solution is I and III
B i think the answer is for #5
The question ask to find and compute the possible formula for the function below where as A = (-1,32) and B= (1,8). In my own calculation and further computation about the problem and also following the rule of general exponential function, the formula would be y = a*(b^x). I hope this would help
D. I think you meant to say 2/3 x so the only correct answer is d
