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? Complete parts (a) through (d) below. Assume the population is normally distributed. The claim is the null hypothesis. (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 thedecision in the context of the original claim. There is not enough evidence at the 1% level of significance to support the claim that the mean dive duration of a North Atlantic right whale is (Type integers or decimals. Do not round.) equal to 11.6 minutes.

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.
