An oceanographer claims that the mean dive duration of a North Atlantic right whale is 11.6 minutes. A random sample of 33 dive durations has a mean of 12.1 minutes and a standard deviation of 2.1 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. (a) Identify the claim and state Ho and Ha. Ho: Ha: (Type integers or decimals. Do not round.) The claim is the hypothesis. (b) Use technology to find the P-value. Find the standardized test statistic, t. %3= (Round to two decimal places as needed.) Obtain the P-value. (Round to three decimal places as needed.) (c) Decide whether to reject or fail to reject the null hypothesis. Ho because the P-value greater than a. (d) Interpret the decision in the context of the original claim. There Venough evidence at the % level of significance to V the claim that the mean dive duration of a North Atlantic right whale is minutes. (Type integers or decimals. Do not round.)

Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
