The proportion of all US adults who eat popcorn when they go to the movie theater is p = 0.87. A random sample
of 20 US adults was selected and asked if they eat popcorn when they go to the movie theater. Which of the
following is the shape of the sampling distribution of ?
The sampling distribution of is approximately Normal because np = 17.4 > 10.
Because n(1-p) = 2001 - 0.87) = 2.6 < 10, the sampling distribution of ร is not approximately Normal. The
sampling distribution of is skewed right and centered at 0.87.
Because n(1-P) = 2001 - 0.87) = 2.6 < 10, the sampling distribution of is not approximately Normal. Because p
= 0.87 is closer to 1 than 0, the sampling distribution of ร is skewed to the left.
Because n(1-P) 20(1-0.87) = 2.6 < 10, the sampling distribution of ร is not approximately Normal. Because p
= 0.87 is closer to 1 than 0, the sampling distribution of is skewed to the right.

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.
