An oceanographer claims that the mean dive duration of a North Atlantic right whale is 11.6 minutes. A random sample of 36 dive durations has a mean of 12.3 minutes and a standard deviation of 2.3 minutes. At α=0.10 is there enough evidence to reject the​ oceanographer's claim?

An oceanographer claims that the mean dive duration of a North Atlantic right whale is 11.5 minutes. A random sample of 34 dive durations has a mean of 12.2 minutes and a standard deviation of 2.2 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 H Họ: (Type integers or decimals. Do not round.) The claim is the V 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. (Round to three decimal places as needed.) (c) Decide whether to reject or fail to reject the null hypothesis. V Họ because the P-value V greater than a. (d) Interpret the decision in the context of the original claim.

In a random sample of 75 eighth grade students scores on a national mathematics assessment test has a mean score of 266. The test result prompts a state school administration to declare that the mean score for the stated eighth graders on this exam is more than 260. Assume the population standard deviation is 34. At a=0.09, is there enough evidence to support the administrations claim? Write the claim mathematically and identify Ho and Ha Find the standardized test statistic z, and its corresponding area

An oceanographer claims that the mean dive duration of a North Atlantic right whale is 11.6 minutes. A random sample of 32 dive durations has a mean of 12.5 minutes and a standard deviation of 2.1 minutes. At a = 0.01 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: Hạ: (Type integers or decimals. Do not round.) The claim is the hypothesis. (b) Use technology to find the P-value.Obtain the P-value. P=0 (Round to three decimal places as needed.) (c) Decide whether to reject or fail to reject the null hypothesis. V Ho because the P-value V greater than a. (d) Interpret the decision in the context of the original claim.
