B. Mean, Mode and Median are always equal when data follows normal distribution.
C. Mean, Mode and Median are always equal when data follows binomial distribution with odd number of sampling points.

Given below are two statements.
Assertion (A):
Security has services like confidentiality, integrity, authentication, access control, et
C.
Reason (R):
Encryption, digital signature, MD5 and secure hash algorithm may be used for authentication and confidentiality, et
C.

Given below are two statements.
Assertion (A):
A random sample of size \(25\) is taken, resulting in a sample mean of \(17.45\) and a sample standard deviation of \(3.6\). Assuming \(H_0:
\mu=18,\ H_1:
\mu\neq18\), the standard error calculated is \(0.72\).
Reason (R):
The standard error for hypothesis testing is calculated using \(\frac{s}{\sqrt{n}}\).

C. \(\mu=37,\ \sigma=5,\ P(X>35)\);
D. \(\mu=156,\ \sigma=10,\ P(X>170)\).
