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 the margin of error M as such

In which
is the standard deviation of the population and n is the size of the sample.
In this problem, we have that:
. So


So the correct answer is:
1.165.
Answer:
1 pound of avocado costs $1.8.
Step-by-step explanation:
This problem is just a simple division problem. We jest need to divide the given values to get the answer. For our problem, to know the price of 1 pound of avocado, we need to divide the $9 by 5 since the problem stated that the price of 5 pounds of avocados is $9.
Given:
5 pounds avocados = $9
Required:
cost of 1 pound of avocado
Solution:
$9 / 5 pounds = $1.8/pound
1 pound avocado = $1.8
Notice from the first line of solution, the unit became $ per pound. This means that we did the right operation since we are looking for the price per pound.
To check if we computed for the correct value, we should multiply $1.8 to 5. If the answer from doing this is $9, then our answer is correct.
Checking:
$1.8 * 5 = $9
Therefore, the cost of 1 pound of avocado is $1.8
