Note that the sample space of X is not unique. For example, if Xâ¼Ber(p), then both {0,1} and R can serve as a sample space. However, in general, we associate a random variable with its smallest possible sample space (which would be {0,1} if Xâ¼Ber(p)). Find the smallest sample space for each of the following random variables. X1â¼Poiss(λ), a Poisson random variable with parameter λ : {0,1} {xâZ:xâ¥0} [0,[infinity]) (â[infinity],[infinity]).

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.

well if you have a decimal you have to line them up and make sure the you have everything   straight and then add or subtract some thing with   division and   multiplying so just like them up
