Suppose the doctors at a local office take a health survey of 100100 adult female patients with similar weight who have had appointments in the last week. According to their medical file, the 100100 participants all weigh between 140−149140−149 lbs. One of the survey questions asks participants to list their current weight. The accompanying tables show the relative frequency of weights measured by the physician for the 100100 participants and the relative frequency of weights recorded in the survey for the 100100 participants. Note that some of the weights reported in the survey did not fall between 140−149140−149 lbs.   Select the statements that are accurate regarding the given data sets. (a) More women in this survey weigh 140140 lbs than any other reported weight. (b) When reported by the individual, weights are often rounded to the nearest 55 lbs. (c) The data suggest that adult women tend to round down their weight. (d) Survey results are just as accurate when participants are asked their weight as when they are weighed with a scale.

According to their medical file, the 100100 participants all weigh between 140−149140−149 lbs. One of the survey questions asks participants to list their current weight. The accompanying tables show the relative frequency of weights measured by the physician for the 100100 participants and the relative frequency of weights recorded in the survey for the 100100 participants. Note that some of the weights reported in the survey did not fall between 140−149140−149 lbs.
