1(a)Consider the following function for a value of c. f(x)= {2/7 cx, 0≤x≤2 2c(3−x) , 2≤x≤4 0, otherwise Comment on the output of these probabilities below, what will be the conclusion of your output. (i)Evaluate c (ii)find (a) p(1≤x≤2) (b) p(x>2).
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.
1(a)Consider the following
f(x)= {2/7 cx, 0≤x≤2
2c(3−x) , 2≤x≤4
0, otherwise
Comment on the output of these probabilities below, what will be the conclusion of your output.
(i)Evaluate c
(ii)find (a) p(1≤x≤2)
(b) p(x>2).
(b) It is known that only 60% of a defected computer can be
repaired. A sample of 8 computers is selected randomly, find
the
(i) At most 3 computers can be repaired.
(ii) 5 or less can be repaired
(iii) None can be repaired
