Question

I need help with part C only.  

Suppose a simple random sample of size n= 75 is obtained from a population whose size is N = 10,000 and whose population proportion with a specified characteristic is p=0.6. Complete parts (a) through (c) below. 0A = 0.056569 (Round to six decimal places as needed.) p (b) What is the probability of obtaining x = 48 or more individuals with the characteristic? That is, what is PCô20.64)? PCÔ 20.64) = 0.2389 (Round to four decimal places as needed.) (c) What is the probability of obtaining x = 39 or fewer individuals with the characteristic? That is, what is Plộ 0.52)?

Answer 1
