An Internet survey first asked a sample of 2,065 men and women how many sexual partners they'd had altogether. When subsequently asked about their truthfulness in responding to the question, 5% said they had lied.
a. If the original survey had been used to estimate the mean number of sexual partners for men and women in general, would it result in bias due to a nonrepresentative sample or bias due to inaccurately assessing a variable's values?
b. What notation do we use for the number 0.05?
c. How do we denote the unknown proportion of all people who would lie when answering such a question?
