An oceanographer claims that the mean dive duration of a North Atlantic right whale is 11.6 minutes. A random sample of 35 dive durations has a mean of 12.4 minutes and a standard deviation of 2.3 minutes. At a = 0.01 is there enough evidence to reject the oceanographer's claim? Complete parts (a) through (d) below. Assume the population is normally distributed. (b) Use technology to find the P-value. Find the standardized test statistic, t. t= 2.06 (Round to two decimal places as needed.) Obtain the P-value. P= 0.047 (Round to three decimal places as needed.) (c) Decide whether to reject or fail to reject the null hypothesis. Fail to reiect H. becauro th
