In a survey of a group of men, the heights in the 20-29 age group were normally distributed, with a mean of 69.3 inches and a standard deviation of 3.0 inches. a study participant is randomly selected. complete parts (a) through (d) below. ? (a) find the probability that a study participant has a height that is less than 66 inches. the probability that the study participant selected at random is less than 66 inches tall is __
? (round to four decimal places as? needed.)
(b) find the probability that a study participant has a height that is between 66 and 71 inches. the probability that the study participant selected at random is between 66 and 71 inches tall is
? (round to four decimal places as? needed.)
? (c) find the probability that a study participant has a height that is more than 71 inches. the probability that the study participant selected at random is more than 71inches tall is
? (round to four decimal places as? needed.)
? (d) identify any unusual events. explain your reasoning. choose the correct answer below.

Listed below are time intervals (min) between eruptions of a geyser. assume that the "recent" times are within the past few years, the "past" times are from around 20 years ago, and that the two samples are independent simple random samples selected from normally distributed populations. do not assume that the population standard deviations are equal. does it appear that the mean time interval has changed? is the conclusion affected by whether the significance level is 0.10 or 0.01? recent 78 90 90 79 57 101 62 87 71 87 81 84 57 80 74 103 62 past 88 89 93 94 65 85 85 92 87 91 89 91 follow the steps of hypothesis testing, including identifying the alternative and null hypothesis, calculating the test statistic, finding the p-value, and making a conclusions about the null hypothesis and a final conclusion that addresses the original claim. use a significance level of 0.10. is the conclusion affected by whether the significance level is 0.10 or 0.01? answer choices below: a) yes, the conclusion is affected by the significance level because h0 is rejected when the significance level is 0.01 but is not rejected when the significance level is 0.10. b) no, the conclusion is not affected by the significance level because h0 is not rejected regardless of whether a significance level of 0.10 or 0.01 is used. c) yes, the conclusion is affected by the significance level because h0 is rejected when the significance level is 0.10 but is not rejected when the significance level is 0.01. d) no, the conclusion is not affected by the significance level because h0 is rejected regardless of whether a significance level of 0.10 or 0.01 is used.
