Hi. I need to know the test statistic, P-value, a null hypothesis conclusion, and a final conclusion.

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 77 91 89 80 57 99 61 88 70 89 83 84 56 80 74 102 60 Past 89 88 93 94 65 84 86 92 87 91 88 91 Let u, be the recent times and let 2 be the past times. What are the null and alternative hypotheses? OA. Ho: My # H2 OB. Ho: H1 = H2 H: My = H2 H : H1 > H2 O C. Ho: My
