Step-by-step explanation:
We are given the following in the question:
Proportion of student who voted Republican in the last election = 50%
Standard error = 5% = 0.05
95% confidence interval:
Putting values, we get,
is the required confidence interval.
Answer:
Step-by-step explanation:
Both functions are linear, as the highest power of x is 1 in each case.
The function represented by the table has a slope of 6, since each unit increase in x results in a unit increase of 6 in y.
The function g(x) = 2x + 6 has a slope of 2.
The y intercept of f(x) is (0, -6), which we can read directly from the table.
The y int. of g(x) is 6, which can be read directly from y = 2x + 6.
g(x) has the greater y-intercept: +6 versus -6.
