Since the test statistics<u> is outside </u>the rejection region , <u>we fail to reject </u>the null hypothesis ,There<u> is no</u> statistically significant evidence to reject the claim
Step-by-step explanation:
From the question we are told that
The claim is 
Hence
The null hypothesis is 
The alternative is 
Generally the test statistics is mathematically represented as

=> 
=> 
Generally the degree of freedom is mathematically represented as



From the student t-distribution table the critical value of
at a degree of freedom of 8 is

Since the
is outside the rejection region , we fail to reject the null hypothesis ,There is no sufficient evidence to reject the claim
Answer:
140 in^3
Step-by-step explanation:
The volume formula can be written as ...
A = Bh
Marcia found B = 20 in^2, so we can use that in the formula, along with h = 7 in.
A = (20 in^2)(7 in)
A = 140 in^3
The volume of the box is 140 cubic inches.
