Answer:
The 95% confidence interval for those opposed is: (0.298, 0.334).
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 .
For this problem, we have that:
1786 of the 2611 were in favor, so 2611 - 1786 = 825 were opposed. Then
95% confidence level
So , z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:
The upper limit of this interval is:
The 95% confidence interval for those opposed is: (0.298, 0.334).
The whole number of minutes that Gianna complete each week as a function of x and y:
Since the above number is greater than 450 minutes, we get the inequality:
Also, "she can complete at most 10 workouts this week" so we deduce the inequality:
Therefore, the system of inequalities is the following:
The above system has many solutions, for example :
