Adults were surveyed about how often they are late to work. Their responses are summarized in the relative frequency bar graph in Fig. 134.

a. Find the proportion of those surveyed who say they are late to work every day.
b. Find the proportion of those surveyed who say they are NOT late to work every day.
c. Find the proportion of those surveyed who say they are late to work less than once a month OR never.
d. Find the proportion of those surveyed who say they are late to work at least once a week.
e. Explain why there is probably response bias. If there were no response bias, would the relative frequency for the €œNever€ category likely be larger or smaller?
