Question

Let X be the amount of tune (in hours) the wait is to get a table at a restaurant. Suppose the cdf is represented by F(x) = {0 x 4| Use the cdf to determine P(X lessthanorequalto 4/3). a) 0.1494 b) 0 0.3111 c) 0.1111 d) 0.8889 e) 0.0494 f) None of the above Let X be the amount of tune (in hours) the wait is to get a table at a restaurant. Suppose the cdf is represented by F(x) = {0 x 2| Use the cdf to determine P(0.5 lessthanorequalto X lessthanorequalto 1.75). a) 0.2181 b) 0.2969 c) 0.7031 d) 0.7656 e) 0.4362 f) None of the above

Explanation / Answer

from baover P(X<4/3)= (4/3)2/16 =1/9=0.1111

option C is correct

2) P(0.5<X<1.75)=(1.75)2/4 -(0.5)2/4 =0.7031

option C
