Answer:
We need a sample size of 1068.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
The margin of error is:
95% confidence level
So , z is the value of Z that has a pvalue of , so .
In this problem:
We need a sample size of n.
n is found when
We do not know the exact proportion, so we use , which is when we are are going to need the largest sample size. So
Rounding up
We need a sample size of 1068.

Step-by-step explanation:
Like bases, you add the powers
Answer:
{3, 5, 7, 9, 11}
Step-by-step explanation:
Domain of a function is the set of all the allowable values that can be used as an input to the function. In easy words, we can just say this: The set of all the inputs to a function comprises the Domain of the function.
Domain consists of the values of independent variable on which some other variable depends and give some output result. From the given table we can see that there are two variables: Number of hours(x) and the Cars Produced(y).
Number of cars produced depend on the number of hours the auto factory remains open. So, number of hours is the independent or the input variable and all the values of this variable will form the Domain of the function represented by the table.
So, the Domain of the function is: {3, 5, 7, 9, 11}
