Suppose that a random sample of 105 Americans is obtained. Complete parts (a) through (c) mean (a) Describe the sampling distribution of p. Choose the correct answer below value of i A The distribution of p can be approximated by a normal distribution with -0 76 and -0 083358 OB. The distribution of p can be approximated by a normal distribution with -0 76 and o 0 041679 C. The distrbution of p cannot be approximated by the normal distrbution Instead, a binomial distribution with n-105 and Click to select your answer and then click Check Answer. D=0.76 should be used. Check Answer Clear All parts remaining

Explanation / Answer

Ans:

Given that

p=0.76

n=105

sampling distribution of sample proportions:

mean=p=0.76

standard deviation=sqrt(0.76*(1-0.76)/105)=0.041679

Option B is correct.
