Listed below are time intervals (mn) between eruptions of a geyser Assume that the recent times are within the past fow yoars, 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 78 91 88 78 56 10063 8071 88 82 83 57 80 74 10160 Past 88 BB 93 94 64 80 85 92 88 91 90 91 Let Hy be the recent times and lot be the past times What are the null and alternative hypotheses?

P value - (Round to three decimal places as needed) Make a conclusion about the nullfiypothesis and a final conclusion that addresses the original claim Use a significance level of 0 10 Hy because the value is the significance level. There sufficient evidence that the mean time interval has changed is the conclusion affected by whether the significance lovelis 0.10 or 001? O A Yes, the conclusion is affected by the significance Nivel because He is rejected when the significance level is 0.01 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 level is 0.10 but is not rejected when the significance lovelis 0.01 OC. No, the conclusion is not affected by the significance level because He is rejected regardiess of whether a significance lovel of 0 10 or 0.01 is used OD. No, the conclusion is not affected by the significance level because Hy is not rejected regardless of whether a significance level of 0 10 or botsused
