Question 469617: Can a kind soul help me with my last killer homework problem? It states:
With probability 0.05 a robotic reporter that works for MEOW NEWS will make a false statement.
Suppose the reporter produced 1900 statements last week.

13. What is the probability that 85 or fewer of those statements were false? Round answer to four places after the decimal point.
P(0<= x <= 85) = binomcdf(1900,0.05,85) = 0.1586
but its wrong...
14. What is the probability that 124 or more of those statements were false? Round answer to four places after the decimal point.
P(124 <= x <= 1900) = 1 - binomcdf(1900,0.05,123) = 0.0019
also wrong... HELP!!!

13)
p=.05, q=.95 n=1900

P(0<= x <= 85.5)
z=(x-mu)/sigma=(85.5-95)/9.5=-1
Area under the normal curve is .1587
