In a large city, 55% of people pass the drivers' road test. Suppose that every day, 200 people independently take the test. Complete parts (a) through (d) below. a. What is the number of people who are expected to pass? The expected number is 110. (Round to the nearest whole number as needed.) b. What is the standard deviation for the number expected to pass? The standard deviation is. (Round to the nearest whole number as needed.)

Expert Solution
Step 1
We have given that
p = 55% = 0.55
n = 200
Here we will use binomial distribution because probability of success is fixed out of fixed number of trials
X ~Binomial(n, p)
X ~ Binomial (200, 0.55)
