Answer:
Step-by-step explanation:
The Volume of a rectangular prism is expressed as;
V = Base area * height of prism
Given
Volume of prism V = 7,280 cubic inches.
height of prism = 26in
Required
Base Area
Substitute the given parameter into the formula;
7280 = 26B
B = 7280/26
B = 280in²
Hence the area of the newspaper on the bottom of the cage is 280in²
280

Answer:
We can say at 99% confidence that the true mean is between (91.674;98.326)
Step-by-step explanation:
Data given
represent the sample mean
population mean (variable of interest)
s=6.6 represent the sample standard deviation
n=30 represent the sample size
The confidence interval for the mean is given by the following formula:
(1)
We need to find the critical value and we need to find first the degrees of freedom, given by:
Since the Confidence is 0.99 or 99%, the value of and , and we can use excel, a calculator or a table to find the critical value. The excel command would be: "=-T.INV(0.005,29)".And we see that
And replacing we got:
We can say at 99% confidence that the true mean is between (91.674;98.326)
