An oceanographer claims that the mean dive duration of a North Atlantic right whale is 11.6 minutes. A random sample of 35 dive durations has a mean of 12.4 minutes and a standard deviation of 2.3 minutes. At a = 0.01 is there enough evidence to reject the oceanographer's claim?

of 2.3 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.
(b) Use technology to find the P-value. Find the standardized test statistic, t.
t = 2.06
(Round to two decimal places as needed.)
Obtain the P-value.
P = 0.047
(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 1% level of significance to reject the claim that the mean dive duration of a North Atlantic right whale is
11.6 minutes.
