A)

B)

C)

D)

**2)** “If is continuous in then for any in that interval, we shall have a polynomial such that

B) finite.

C) finite.

D) finite.

**8)** In measuring trend by the method of moving average, the no, of terms to be considered for averaging is decided by

A) the length of the shortest circle.

B) the no of cycles.

C) the length of cycles.

D) none of the above.

**9)** If are random observations, then

is

A) a random variable, but not a stochastic process.

B) a stochastic process.

C) neither a random variable nor a stochastic process.

D) a stochastic process, but not a random variable.

**10)** The Weiner stochastic process with constant time is known in the theory of statistics as the
