Three national news networks are trying to estimate what percentage of American voters support a particular presidential candidate. To estimate the
population parameter, each of the three networks collects data from a simple
random sample of voters. Here are the numbers of voters in the networks'
random samples:
• Network A: 2250 voters sampled
• Network B: 2800 voters sampled
• Network C: 2500 voters sampled
Which sample is likely to have the least variability?
A. The Network A sample
Ο Ο Ο
B. The Network B sample
O C. The Network C sample

At the olympic games, many events have several rounds of competition. one of these events is the men's 100-meter backstroke. the upper dot plot shows the times (in seconds) of the top 8 finishers in the final round of the 2012 olympics. the lower dot plot shows the times of the same 8 swimmers, but in the semifinal round. which pieces of information can be gathered from these dot plots? (remember that lower swim times are faster.) choose all answers that apply: a: the swimmers had faster times on average in the final round. b: the times in the final round vary noticeably more than the times in the semifinal round. c: none of the above.
