Listed below are time intervals (min) between eruptions of a geyser Assume that the ocent 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 solcted from normally distributed populations. Do not assume that the population standard deviations are equat Does it appear that the meantime interval has changed? Is the conclusion affected by whether the significance level is o 10 or 001?

Is the conclusion affected by whether the significance level is 0 10 or 001? O A. Yes, the conclusion is affected by the significance level because He is rejected when the significance levels 001 but is not rejected when the significance level is 0.10 OB. Yes, the conclusion is affected by the significance level because He is rejected when the significance levels 0 10 but is not rejected when the signaticance levolis 0.01 OC. No, the conclusion is not affected by the significance level because Hy is rejected rogardless of whether a significance level of 0.10 or 0.01 is used OD. No, the conclusion is not affected by the significance level because He is not rejected regardless of whether a significance level of 0 10 or 0.01 is used Submit quiz
