Aperson's protein requirement is the amount of protein they must consume in a day to maintain a stable weight, muscle mass, etc. a group of researchers wanted to know if the mean protein requirement (in grams of protein per day per kg of body weight) is the same for young adult males and females. the protein requirements of 12 males and 11 females was determined and presented: males females0.74 0.820.76 0.800.59 0.680.44 0.510.46 0.540.51 0.630.63 0.700.29 0.800.43 0.490.59 0.740.47 0.620.72a) is this a designed experiment or observational study? justify your answer. b) construct a 99% confidence interval for the difference in mean protein requirement of young adult males and females. assume that the populations are normally distributed.

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.
