Statistics and Probability Concepts Quiz

Question 1

• Variance of Poisson Distribution is $\lambda$
• Normal distribution is applied for Continuous Random Variable
• When Correlation Coefficient value is -0.2 then correlation is Weak negative correlation
• Trapezoidal rule gives exact value of integral if integrand is Linear
• The area under a standard normal curve is 1
• There are 12 elements in the sample space (S) when tossing a coin and rolling a die together.
• The value of the divided difference $[x_0, x_1]$ is 1
• For larger values of 'n', Binomial Distribution tends to Poisson Distribution
• The mean of the probability distribution of the number of heads obtained in 676 flips of a balanced coin is 338
• In Simpson's $\frac{1}{3}$ rd Rule, $f(x)$ is assumed to be polynomial of Degree Two

Question 2 (A)

• The probability of transmitting a 1 is 0.4
• The probability of transmitting a 0 is 0.6
• The probability of correctly receiving a 0 is 0.90
• The probability of correctly receiving a 1 is 0.95
• The probability of incorrectly receiving a 0 is 0.10
• The probability of incorrectly receiving a 1 is 0.05

Question 2 (B)

• A system of linear equations is diagonally dominant if the absolute value of the diagonal element in each row is greater than the sum of the absolute values of the other elements in that row.
