A simple random sample of 30 men from a normally distributed population results in a standard deviation of 12.5 beats per minute. The normal range of pulse rates of adults is typically given as 60 18 100 Beas per thumb is applied to that normal range, the result is a standard deviation of 10 beats per minute. Use the sample results with a 0.10 significance level to test the claim that pulse rates of men have a standard deviation equal to 10 beats per mi Complete parts (a) through (d) below. a. Identify the null and alternative hypotheses. Choose the correct answer below. O B. Ho: 02 10 beats per minute A Ho: a= 10 beats per minute H:a< 10 beats per minute H:o 10 beats per minute OD. Ho: a = 10 beats per minute H:a< 10 beats per minute OC. Ho: o 10 beats per minute H:0= 10 beats per minute b. Compute the test statistic. (Round to three decimal places as needed.)

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.
