what is the standard deviation of the number of A Recoveries among 48 patients when the probability of Recovering is 0.75​

Answer»

ANSWER:

The answer is 3.

Step-by-step explanation:

Standard deviation = √npq

Where "n" is the number of PATIENTS = 48

"p" is the CHANCES of success = 0.75

"q" is the chance of failure = 0.25

Therefore,

Standard deviation = √ 48 X 0.75 x 0.25  

                             = √9 = 3

Thus the value of standard deviation is 3.
