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 12.3 minutes and a standard deviation of 2.3 minutes. At a = 0.05 is there enough evidence to reject the oceanographer's claim? Complete parts (a) through (d) below. Assume the population is normally distributed. (a) Identify the claim and state Ho and Ha Ho: 1 = 11.4 Ha: H # 11.4 (Type integers or decimals. Do not round.) The claim is the null hypothesis (b) Use technology to find the P-value. Find the standardized test statistic, t. 1= 2.25 /Bound In hun da " nandad ) Question is complete.

Complete parts (a) through (d) below. Assume the population is normally distributed. P= 0.032 (Round to three decimal places as needed.) (c) Decide whether to reject or fail to reject the null hypothesis Reject Ho because the P-value is not greater than a. (d) Interpret the decision in the context of the original claim. There is enough evidence at the 5 % level of significance to reject the claim that the mean dive duration of a North Atlantic right whale is equal to 11.4 minutes. (Type integers or decimals.
