An oceanographer claims that the mean dive depth of a North Atlantic right whale is 113 meters. You suspect that this claim is not true. In order to refute the oceanographer's claim, you obtain a random sample of 38 dive depths with a mean of 95 meters and a standard deviation of 43.5 meters. State the null and alternative hypotheses of this test. Null Hypothesis (Ho): Alternative Hypothesis (HA): H[? ) To test our hypothesis, we will assume that u = The distribution of sample means follows a ( Select an answer distribution with degrees of freedom. The value of our test statistic is The p-value for this hypothesis test is Report answer accurate to four decimal places. Is the result considered significant at the a = 0.05 level of significance? No. The result is not significant because the p-value is > a. Yes. The result is significant because the p-value is > a. Yes. The result is significant because the p-value is < a. No. The result is not significant because the p-value is < a. We conclude that We can dispute the oceanographer's claim that the mean dive depth of a North Atlantic right whale is 113 meters at the 0.05 level of significance. We cannot dispute the oceanographer's claim that the mean dive depth of a North Atlantic right whale is 113 meters at the 0.05 level of significance.
