Answer:
A 99% confidence interval will be wider than a 95% confidence interval
Step-by-step explanation:
From the question we are told that
The 95% confidence interval for for the mean foot length for students at the college is found to be 21.709 to 25.091 cm
Generally the width of a confidence interval is dependent on the margin of error.
Generally the margin of error is mathematically represented as
From the above equation we see that
Here 
is the critical value of the half of the level of significance and this value increase as the confidence level increase
Now if a 99% confidence level is used , it then means that the value of
will increase, this in turn will increase the margin of error and in turn this will increase the width of the confidence interval
Hence a 99% confidence interval will be wider than a 95% confidence interval
Answer:
Step-by-step explanation:
Multiply the three dimensions
12 x 6 x 8 = 576 cm^3
An=-31+(n-1)-11 find the eleventh term
a11 = -31 + (-11) (11-1)
a11 = -31 +-11(10)
a11 =-31 +-110
a11 = -142
Hi there!
The general formula of A line in slope-intercept form is the following:
In this formula m represents the slope of the line. Therefore, we can conclude that m = 2/5.
We also know that the line passes through the point (-3, -1) and we can therefore substitute this coordinate into the formula of the line.
x = -3 and y = -1
Multiply first.
And finally add 1 1/5 to both sides of the equation.
We can now switch sides.
Now we've found our value of n, which we can substitute into the formula of our line. Hence, in slope-intercept form, we find the following:
