Consider a population proportion p = 0.68. calculate the expected value and the standard error of with n = 20. is it appropriate to use the normal distribution approximation for ? calculate the expected value and the standard error of with n = 50. is it appropriate to use the normal distribution approximation for ?

a) 0.68, 0.1043, b) 0.68, 0.066

Step-by-step explanation:

Since we have given that

p = 0.68

n= 20

Expected value = 0.68

So, Standard error would be

if n = 50

Expected value = 0.68

So, Standard error would be

In both the cases,

Yes it is appropriate to use the normal distribution for expected value and standard error.
