Answer:
n=1705
Step-by-step explanation:
The margin of error is the range of values below and above the sample statistic in a confidence interval.
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
Assuming the X follows a normal distribution
And the distribution for is:
We know that the margin of error for a confidence interval is given by:
(1)
The next step would be find the value of ,
and
Using the normal standard table, excel or a calculator we see that:
If we solve for n from formula (1) we got:
And we have everything to replace into the formula:
And if we round up the answer we see that the value of n to ensure the margin of error required mm is n=1705.
Answer:
The slope is undefined
Step-by-step explanation:
Find slope by using the slope formula,
Use the given points and insert the x's and y's to solve for slope
(-7, -7) (-7, 1)
m = undefined
The slope for the given point is undefined because it is impossible to divide a number by 0
