Question

For a sample size of n=26 and a population parameter of p=0.4, a normal curve can be used to approximate the binomial probability histogram.

True or false?

Answer 1

you have to check that n*p >= 5 and n*(1-p)>= 5

Answer 2

@perl np = 26 * 0.4 = 10.4 > 5 would this be false

Answer 3

check 26(.4) and 26(.6)

if they are both bigger than 5 you should be fine

Answer 4

2.6 = 10%

they are fine

Answer 5

@amistre64 so it is false?
