Suppose that a recent poll found that 40% of adults in a certain country believe that the overall state of moral values is poor.

shusha [124]

Answer:

Step-by-step explanation:

Let X be the no of adults whose feelings the state of morals is poor.

X has two outcomes and each trial is independent of the other

X is Bin with p = probability for success in each trial =40%=0.40

n=no of adults surveyed = 55

a) The probability that exactly 21 of those surveyed feel the state of morals is poor is

$P(X=21) = 40C21 (0.4)^{21} (1-0.4)^{19} \\=0.03519$

(b) The probability that no more than 22 of those surveyed feel that state of morals is poor is

= $P(X$

(c) The probability that more than22 of those surveyed feel the state of morals is poor is

$P(X>22)\\=1-0.9811\\=0.0119$

(d) The probability that 15 or 16 believe the state of morals is poor is

= $P(X=15)+P(X=16)\\=0.1228+0.1279\\=0.2507$
