QUESTION 8 A bottling company produces bottles that hold 12 ounces of liquid. Periodically, the company gets complaints that their bottles are not holding enough liquid. To test Ho:u= 12 against H:u<12, the company randomly sampled 36 bottles and found that the average amount of liquid held by the bottles was 11.6 ounces with a standard deviation of 0.9 ounce. What conclusion would you make at 0.01 level of significance? O Reject HO because -2.67 < -2.576 O Do not reject HO because -2.67 <-2.576 O Reject HO because -2.67 < -2.326 O Do not reject HO because -2.67 < -2.326 QUESTION 9 rimum error that might occur when we use

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.
