An oceanographer claims that the mean dive duration of a North Atlantic right whale is 11.4 minutes. A random sample of 33 dive durations has a mean of 12.4 minutes and a standard deviation of 2.3 minutes. At x = 0.05 is there enough evidence to reject the oceanographer's claim? Complete parts (a) through (d) below. Assume the population is normally distributed. Ho: Ha: (Type integers or decimals. Do not round.) The claim is the hypothesis. (b) Use technology to find the P-value. Find the standardized test statistic, t. t = (Round to two decimal places as needed.) Obtain the P-value. P = (Round to three decimal places as needed.) (c) Decide whether to reject or fail to reject the null hypothesis. Ho because the P-value (d) Interpret the decision in the context of the original claim. There enough evidence at the % level of significance to (Type integers or decimals. Do not round.) greater than α. support reject the claim that the mean dive duration of a North Atlantic right whale is minutes.
