Question
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.
There
V enough evidence at the % level of significance to
the claim that the mean dive duration of a North Atlantic right whale is
minutes.
(Type integers or decimals. Do not round.)
