Explanation Given: A list of 10 best-sellers is there to identify his or her favorite book asked from each of 5 people Formula used: The formula for permutation is, n C r = n ! ( n − r ) ! r ! Probability: The formula for probability is, P ( E ) = Number of elements in E Number of elements in S = n ( E ) n ( S ) Probability of the complementary Event: For any events E , P ( E ) = 1 − P ( E ′ ) . Calculation: Define the event A denotes that at least two people to identify the same book then the event A ′ denotes every person identifies different book. Here, there are totally 10 best sellers. From the 10 best sellers each of the 5 people is asked to identify can be done in 10 5 ways. That is, n ( S ) = 10 5 , and from the 10 best sellers selecting 5 people can be done in 10 P 5 ways

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 re…

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.

Suppose an experiment was conducted to compare the mileage(km) per litre obtained by competing brands of petrol I,II,III. Three new Mazda, three new Toyota and three new Nissan cars were available for experimentation. During the experiment the cars would operate under same conditions in order to eliminate the effect of external variables on the distance travelled per litre on the assigned brand of petrol. The data is given as below: Brands of Petrol Mazda Toyota Nissan I 10.6 12.0 11.0 II 9.0 15.0 12.0 III 12.0 17.4 13.0 (a) Test at the 5% level of significance whether there are signi cant differences among the brands of fuels and also among the cars. [10] (b) Compute the standard error for comparing any two fuel brands means. Hence compare, at the 5% level of significance, each of fuel brands II, and III with the standard fuel brand I. [10]
