An oceanographer claims that the mean dive duration of a North Atlantic right whale is 11.3 minutes. A random sample of 34 dive durations has a mean of 12.4 minutes and a standard deviation of 2.2 minutes. At α=0.10 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 H0 and Ha. (b) use technology to find the P value. Find the standardized test statistic, t. t=______ Obtain the P value P=_______ (c)Decide whether to reject or fail to reject the null hypothesis: (d) Interpret the decision in the context of the original claim:
