An oceanographer claims that the mean dive duration of a North Atlantic right whale is 11.7 minutes, A random sample of 35 dive durations has a mean of 12.5 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. (a) Identify the claim and state Ho and H. Ho: 11.7 * 11.7 (Type integers or decimals. Do not round.) The claim is the null hypothesis. (b) Use technology to find the P-value. Find the standardized test statistic, t. (Round to two decimal place as needed.)
