You are planning to use a sample proportion to estimate a population proportion, p. A sample size of 100 and a confidence level of 95% yielded a margin of error of 0.025. Which of the following will result in a smaller margin of error? I: Increasing the sample size while keeping the same confidence level II: Decreasing the sample size while keeping the same confidence level III: Increasing the confidence level while keeping the same sample size IV: Decreasing the confidence level while keeping the same sample size

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
