Answer:
The 80% confidence interval for the mean consumption of meat among people over age 23 is between 4 and 4.2 pounds.
Step-by-step explanation:
We have that to find our
level, that is the subtraction of 1 by the confidence interval divided by 2. So:

Now, we have to find z in the Ztable as such z has a pvalue of
.
So it is z with a pvalue of
, so 
Now, find M as such

In which
is the standard deviation of the population and n is the size of the sample.

The lower end of the interval is the mean subtracted by M. So it is 4.1 - 0.07 = 4.03 pounds
The upper end of the interval is the mean added to M. So it is 4.1 + 0.07 = 4.17 pounds
Rounded to one decimal place
The 80% confidence interval for the mean consumption of meat among people over age 23 is between 4 and 4.2 pounds.
Answer:
Explained Below
Step-by-step explanation:
first we need to turn the equation into point slope form.
3x + 4y = 12
4y = -3x + 12
y = -0.75 + 3
Parallel lines don't have a change in slope because they run parallel. Your answer would be -0.75 or -3/4.
the local maximum is at x = -2.2 and has a value of 72.576
Answer:
The value of function (fog)(x) is 4 x² - 19
Step-by-step explanation:
Given function as :
f(x) = 4 x + 1
g(x) = x² - 5
So , function (fg(x)) can be written as
(fog)(x) = 4 ( x² - 5 ) + 1
Or, (fog)(x) = 4 x² - 20 + 1
Or, (fog)(x) = 4 x² - 19
Hence The value of function (fog)(x) is 4 x² - 19 Answer
Answer:
4(-1)
