More coins Suppose the class in Exercise 11 repeats thecoin-tossing experiment.a) The students toss the coins 25 times each. Use the 68–95–99.7 Rule to describe the sampling distribution model.b) Confirm that you can use a Normal model here.c) They increase the number of tosses to 64 each. Drawand label the appropriate sampling distribution model.Check the appropriate conditions to justify your model.d) Explain how the sampling distribution model changesas the number of tosses increases.
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.
More coins Suppose the class in Exercise 11 repeats the
coin-tossing experiment.
a) The students toss the coins 25 times each. Use the 68–95–
99.7 Rule to describe the sampling distribution model.
b) Confirm that you can use a Normal model here.
c) They increase the number of tosses to 64 each. Draw
and label the appropriate sampling distribution model.
Check the appropriate conditions to justify your model.
d) Explain how the sampling distribution model changes
as the number of tosses increases.
