An oceanographer claims that the mean dive duration of a North Atlantic right whale is 11.7 minutes. A random sample of 32 dive durations has a mean of 12.2 minutes and a standard deviation of 2.3 minutes. At α = 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: Ha: ▼ ▼ (Type integers or decimals. Do not round.)
