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 12.5 minutes and a standard deviation of 2.2 minutes. At o=0.01 is there enough evidence reject the oceanographer's daim? Complete parts (a) through (d) below. Assume the population is normally distributed. (a) Identify the daim and state Ho and Hg. Ho H (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, L (Round to two decimal places as needed.) Obtain the P-value. P-0 (Round to three decimal places needed.) (c) Decide whether to reject or fail to reject the null hypothesis. V Ho because the P-value greater than a (d) Interpret the decision in the context of the original daim. There enough evidence at the % level of significance to (Type integers or decimals. Do not round.) the claim that the mean dive duration of a North Atlantic right whale is minutos.
