Question
Which of the following is a type of malicious software
designed to harm or exploit any computer system?Solution
Explanation: A virus is a type of malicious software designed to infect a computer and potentially cause harm by corrupting data or disrupting system operations. Firewalls are used for security, backups are used for data recovery, and routers are network devices used to direct data traffic.
The null hypothesis in ANOVA one-way classification, the study of the variances due to k different sources, is:
The probability density function of a random variable X is f(x) = ( π /10) sin ( π x /5) ; 0 ≤ x ≤ 5. The first quartile of X is:
For the variables X, Y and Z, rXY = 0.80, rXZ = 0.64, rY Z = 0.79 , then square of multiple correlation coefficient R2 X.Y Z is:

If the multiple correlation coefficient of X1 on X2 and X3 is zero, then:
Let x and y be two variables with variance as 1990 and 796 with 11 and 9 number of observations respectively. The value of F(10, 8) at 5% level of sign...
If the occurrence of events follows Poisson Process with mean rate λ, then inter-occurrence time of events will follow:
The mode of the given data set is 12. The sum of the frequency on both sides of mode are 16. The skewness:
If moment generating function of continuous random variable X is (λ /λ−t) ;t < λ, then E(X3) equals to:
