The American Nurses Association can calculate the probability that a surveyed nurse had over 25 years of experience to be 1,189/4,507 0.26.
a. If the ANA wants to draw conclusions about the probability that any nurse has over 25 years experience, is it mainly concerned with data production, displaying and summarizing, probability, or statistical inference?
b. If older nurses are less likely to complete an online survey than younger nurses, would 0.26 tend to be an overestimate or an underestimate for the probability that any nurse has over 25 years' experience?
