Answer:
The critical value for this test is tc=-1.71.
Step-by-step explanation:
We have to calculate the critical value for this hypothesis test.
We have a sample of size n=25, with mean M=4300 and standard deviation s=500.
The population standard deviation is not known, so we will use the sample standard deviation as an estimation and use a t-test.
To calculate the critical value for this problem, we need to know the type of test, significance level and, because is t-test, the degrees of freedom:
The test is one-sided (left tail) test.
The significance level is 0.05.
The degrees of freedom are df=n-1=25-1=24.
Then, using a table for the t-students distribution, we get the critical value:
The critical value for this test is tc=-1.71.
We have been given the dimensions of the rectangular prism.
Lets say that the length, width, and height of the rectangular prism are:
Length
Width
Height
Volume of a rectangular prism is given by:
Plugging the values of length, width, and height, we get:
Total volume of the prism
(we have used
)
So, the expression for the total volume of the prism is:
