Question

consider the following binomial experiment: 290 people have been exposed to the flu. if the probability that a person contracting the flu on exposure is 0.37, find the variance of these 290 people contracting the flu. a) 182.7000 b) 39.7010 c) 0.2331 d) 67.5990 e) 493.7838 f) none of the above.

Adela · Answer

The  variance  of the 290 people  contacting the flu , given the probability of contacting the flu, is d) 67.5990    How to find the variance ?    When given the  probability  in a  binomial experiment,  and the number of people in the experiment, you can find the variance by the formula:  = Number of subjects in experiment x Probability of contacting the flu x ( 1 - probability of contacting the flu)    Number of subjects in experiment = 290 people   Probability of  contacting  the  flu  = 0.37    The  variance  of the people contacting the flu is: = 290 x 0.37 x ( 1 - 0.37)  = 290 x 0.37 x 0.63  = 67.5990    Find out more on  binomial experiments  at https://brainly.com/question/14307841    #SPJ1
