Use a t-test to test the claim about the population mean u at the given level of significance a using the given sample statistics. Assume the population is normally distributed. Claim: u2 8300; a = 0.01 Sample statistics: x= 8000, s = 480, n= 25 ... What are the null and alternative hypotheses? A OA Hu#8300 Hp= 8300 OC. Ho u58300 Hp> 8300 Β. H με 8300 Hu<8300 OD. Ho: = 8300 Hiu#8300 What is the value of the standardized test statistic? B The standardized test statistic is. (Round to two decimal places as needed.) ine StaIIuarue What is the P-value of the test statistic? P-value = (Round to three decimal places as needed.) Decide whether to reject or fail to reject the null hypothesis. Choose the correct answer below D A. Fail to reject Ho. There is not enough evidence to support the claim. B. Fail to reject Ho. There is enough evidence to support the claim. O C. Reject Ho. There is enough evidence to support the claim. O D. Reject Ho. There is not enough evidence to support the claim.

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.
