19.The drug company Alcide wants to know if their disinfectant can reduce a certain percentage of bacteria between the amounts of 20-40 colonies per petri dish. The average disinfectant kills M=25 colonies with a s=7 colonies. a. Write this out in probability notation. b. Draw a curve, include the numbers and shade in the area that Alcide is interested finding out about. c. Using the information above, what proportion of the cells will die between 20 and 40 colonies? Hint! You will have to look at the unit normal table two times to be able to answer this question.
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.
