An oceanographer claims that the mean dive duration of a North Atlantic right whale is 11.3 minutes. A random sample of 33 dive durations has a mean of 12 1 minutes and a standard deviation of 2.2 minutes At 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 Ha 113 (Type integers or decimals Do not round.) The claim is the alternative hypothesis. (b) Use technology to find the P-value. Find the standardized test statistic, t t=2.09 (Round to two decimal places as needed.). Obtain the P-value P=0.045 (Round to three decimal places as needed) (c) Decide whether to reject or fail to reject the null hypothesis. Reject Ho because the P-value is not greater than a (d) Interpret the decision in the context of the original claim There is not 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 0,0 Moto minutes.
