Explanation / Answer

we know that

p = 0.38

now the mean is given as

mean = np = 0.38*6 = 2.28 ~ 2

and SD = sqrt(np*(1-p)) = sqrt(6*0.38*0.62) = 1.18 ~ aprrox 1

anything that falls outside the range

mean +- 2SD , would be considered unuusual

2 +- 2*1

0,4

Hence any value greater than 4 should be considered unusual

Hence X = 5 is unusual

there p value should be greater that alpha 0.05
