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: = 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.

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 p…
