Extracted text: An oceanographer claims that the mean dive duration of a North Atlantic right whale is 11.3 minutes. A random sample of 32 dive durations has a mean of 12.3 minutes and a standard deviation of 2.2 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: 11.3 %3D Ha: 11.3 (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. t= 2.57 (Round to two decimal places as needed.) Obtain the P-value. P= 0.015 (Round to three decimal places as needed.) (c) Decide whether to reject or fail to reject the null hypothesis. Fail to reject Ho because the P-value is greater than a.
