An oceanographer claims that the mean dive duration of a North Atlantic right whale is 11.4 minutes. A random sample of 36 dive durations has a mean of 12.2 minutes and a standard deviation of 2.3 minutes. At a = 0.10 is there enough evidence to reject the oceanographer's claim? Complete parts (a) through (d) below. Assume the population is normally distributed C (a) Identify the claim and state Ho and H₂. Ho: H₂: (Type integers or decimals. Do not round.) The claim is the hypothesis. (b) Use technology to find the P-value. Find the standardized test statistic, t. (Round to two decimal places as needed.)
Obtain the P-value. P= (Round to three decimal places as needed.) (c) Decide whether to reject or fail to reject the null hypothesis. Ho because the P-value greater than a. (d) Interpret the decision in the context of the original claim. There enough evidence at the minutes. (Type integers or decimals. Do not round.) % level of significance to the claim that the mean dive duration of a North Atlantic right whale is
