A Gallup Poll used telephone interviews to survey a sample of 1025 U.S. residents over the age
of 18 regarding their use of credit cards. The poll reported that 76% of Americans said that they
had at least one credit card. Give the 95% margin of error for
Why do we assume p=0.5 in determining the necessary sample size?
When we dont have any idea about the population proportion, no prior estimation was available,
the value 0.5 is used as the estimate for the population proportion. As the proportion can be a
1.) Identify the degree and describe the end behavior of the function:
F(x)=4x^7-x^5+x^3-1
Degree = 7 ("4x^7")
F(x) tends to infinity as x tends to infinity
F(x) tends to negative infinity as x tends to negative infinity
2.) Use the intermediate value the

Increasing is: [2, 4] on the x-axis
Decreasing is: [0,2) on the x-axis
Constant: none
