Types of Bias

Statistics is the study of data collection, organization, analysis, interpretation, and presentation. Statistical bias is a characteristic of a statistical technique or its findings in which the expected value deviates from the actual root quantitative parameter being estimated. According to the actual definition of bias, it refers to the tendency of a statistic to overestimate or underestimate a parameter.

Can you please check my work

An oceanographer claims that the mean dive duration of a North Atlantic right whale is 11.7 minutes. A random sample of 35 dive durations has a mean of 12.5 minutes and a standard deviation
of 2.2 minutes. At a = 0.05 is there enough evidence to reject the oceanographer's claim? Complete parts (a) through (d) below. Assume the population is normally distributed.
Ho:
.....
%3D
11.7
Ha:
# 11.7
(Type integers or decimals. Do not round.)
The claim is the
null
hypothesis.
(b) Use technology to find the P-value. Find the standardized test statistic, t.
t = 2.15
(Round to two decimal places as needed.)
<>
Obtain the P-value.
P = 0.039
(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.
