In San Francisco, 30% of workers take public transportation daily.
a) In a sample of 10 workers, what is the probability that exactly three workers take the public transport daily? [Hint: It is a Binomial Distribution Problem.]
f(3) =
b) In a sample of 10 workers, what is the probability that at least three workers take the public transport daily?
P(x?3)=1-f(0)- f(1)- f(2)f(0) =f(1) =f(2) =P(x?3)=1-f(0)- f(1)- f(2) =
c) How many workers are expected to take the public transportation daily?
E(X) =
d) Compute the variance and the standard deviation of the number of workers that will take the public transport daily.
Var(X) =Standard Deviation =
The sample mean is 50, the t-critical value is 1.96, and the standard error of the sample mean is 2.
