An oceanographer claims that the mean dive duration of a North Atlantic right whale is 11.4 minutes, A random sample of 34 dive durations has a mean of 12.1 minutes and a standard deviation of 2.3 minutes. 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 H, and H Ho: Ha (Type integers or decimals. Do not round.) The claim is the Vhypothesis.
