Suppose that a recent poll found that 44% of adults believe that the overall state of moral values is poor. Complete parts(a) through(c).

(a) For 350 randomly selectedadults, compute the mean and standard deviation of the random variableX, the number of adults who believe that the overall state of moral values is poor.

The mean of X is

nothing

.(Round to the nearest whole number asneeded.)

The standard deviation of X is

nothing

. (Round to the nearest tenth asneeded.)

(b) Interpret the mean. Choose the correct answer below.

A.

For every 350 adults, the mean is the number of them that would be expected to believe that the overall state of moral values is poor.

B.

For every 154 adults, the mean is the maximum number of them that would be expected to believe that the overall state of moral values is poor.

C.

For every 350 adults, the mean is the range that would be expected to believe that the overall state of moral values is poor.

D.

For every 350 adults, the mean is the minimum number of them that would be expected to believe that the overall state of moral values is poor.

(c) Would it be unusual if 169 of the 350 adults surveyed believe that the overall state of moral values ispoor?
