A manufacturer of electronic calculators is interested in studying the proportion of defective units produced. A random sample of 800 calculations contains 20 defectives. You plan to perform an appropriate hypothesis test to determine if there is sufficient evidence to suggest the population proportion of defective exceeds 0.02 at the 0.05 level of significance. Suppose the true population proportion is 0.03. A. (4 pts) What is the power for the test you are planning on performing

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.
