This Question: 3 pts 7 of 8 (3 complete) This Quiz: 20 pts p An oceanographer claims that the mean dive duration of a North Atlantic right whale is 11.7 minutes. A random sample of 34 dive durations has a mean of 12.2 minutes and a standard deviation of 2.1 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. (a) Identify the claim and state Ho and Ha- Ho = 11.7 Ha # 11.7 (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. Fail to reject Ho because the P-value is greater than a (d) Interpret the decision in the context of the original claim. There is 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 Enter your answer in each of the answer boxes. S (0,0) More MeeBook Air 11.7 minutes.
