Use the normal approximation to the binomial distribution to answer this question. fifteen percent of all students at a large university are absent on mondays. if a random sample of 12 names is called on a monday, what is the probability that four students are absent?

0.1289

Step-by-step explanation:

Given : The proportion of all students at a large university are absent on Mondays. :

Sample size :

Mean :

Standard deviation =

Let x be a binomial variable.

Using the standard normal distribution table ,

             (1)

Z score fro normal distribution:-

For x=4

For x=3

Then , from (1)

Hence, the probability that four students are absent =

step-by-step explanation:

if you meant, "on the way from (3, 2) to (3, 14):

x does not change; y increases by 12.
