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 0.017 Recent 77 91 88 79 56 100 62 87 71 89 83 84 57 80 75 103 62 Past 89 87 93 94 64 84 85 92 88 91 90 91 Let , be the recent times and let y be the past times. What are the null and alternative hypotheses? O A HH512 H₂ H = 2 OC Hohh H₂:4H2 O B. Ho: 14 =12 HH vo. Ho:14H Н. В. Да Calculate the test statistic =(Round to two decimal places as needed.)
