Step-by-step explanation:
Given
Perpendicular to
Required
Determine the line equation
An equation has the form
Where
By comparison with
Because the line is perpendicular to , the following relationship exists
i.e. the condition for perpendicularity
Where m1 is the slope of the equation that passes through
So, we have:
The line equation is then calculated using:
Where
So, we have:
Add 11 to both sides

Answer:
(5.097, 7.404)
Step-by-step explanation:
We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 40 - 1 = 39
90% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 39 degrees of freedom(y-axis) and a confidence level of . So we have T = 1.6849
The margin of error is:
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 6.25 - 1.154 = 5.096 hours
The upper end of the interval is the sample mean added to M. So it is 6.25 + 1.154 = 7.404 hours.
The answer is (5.097, 7.404)
