An oceanographer claims that the mean dive depth of a North Atlantic right whale is 122 meters. You suspect that this claim is not true. In order to refute the oceanographer's claim, you obtain a random sample of 37 dive depths with a mean of 130 meters and a standard deviation of 20 meters. State the null and alternative hypotheses of this test. Round answers to 4 decimal places. Use a significance level of ?=0.01. a. H0? : meters b. H1? : meters c. The test statistic is d. The p-value for this hypothesis test is e. The correct decision is: Reject the alternative hypothesis. Reject the null hypothesis. Reject the claim. Do not reject the null hypothesis. f. Is the result considered significant? No. The result is not significant because the p-value is ??. Yes. The result is significant because the p-value is ??. No. The result is not significant because the p-value is >?. Yes. The result is significant because the p-value is >?. g. We conclude that: We can dispute the oceanographer's claim that the mean dive depth of a North Atlantic right whale is 122 meters at the 0.01 level of significance. We cannot dispute the oceanographer's claim that the mean dive depth of a North Atlantic right whale is 122 meters at the 0.01 level of significance.
