Trimmed mean because the mean is very sensitive to extreme values, we say that it is not a resistant measure of center. by deleting some low values and high values, the trimmed mean is more resistant. to find the 10% trimmed mean for a data set, first arrange the data in order, then delete the bottom 10% of the values and delete the top 10% of the values, then calculate the mean of the remaining values. use the axial loads (pounds) of aluminum cans listed below (from data set 30 “aluminum cans” in appendix b) for cans that are 0.0111 in. thick. an axial load is the force at which the top of a can collapses. identify any outliers, then compare the median, mean, 10% trimmed mean, and 20% trimmed mean.

In a sample of 2023 u.s. adults, 373 said franklin roosevelt was the best president since world war ii. two u.s. adults are selected at random from the population of all u.s. adults without replacement. assuming the sample is representative of all u.s. adults, complete parts (a) through (d). (a) find the probability that both adults say franklin roosevelt was the best president since world war ii. the probability that both adults say franklin roosevelt was the best president since world war ii is (round to three decimal places as needed.) (b) find the probability that neither adult says franklin roosevelt was the best president since world war ii. the probability that neither adult says franklin roosevelt was the best president since world war ii is (round to three decimal places as needed.) (c) find the probability that at least one of the two adults says franklin roosevelt was the best president since world war ii. the probability that at least one of the two adults says franklin roosevelt was the best president since world war ii is (round to three decimal places as needed.) (d) which of the events can be considered unusual? explain. select all that apply. the event in part left parenthesis a right parenthesis is unusual because its probability is less than or equal to 0.05. the event in part (b) is unusual because its probability is less than or equal to 0.05. none of these events are unusual. the event in part (c) is unusual because its probability is less than or equal to 0.05.

If jaime wants to find 60% of 320, which table should he use?

The reflexive property of congruence lets you say that ∠pqr ≅
