Question

QUESTION 9 Provide an appropriate response. A simple random sample of size n - 1220 is obtained from a population whose size is N=1,400,000 and whose population proportion with a specified characteristicis p=0.61. Describe the sampling distribution of p. Exactly normal; p=0.61, Op = 0.014 Approximately normal; p = 0.61, Op-0.1304 Exactly normalPp -0.61, op -0.1304 Approximately normal; Hp -0.61,0p -0.014

Answer 1

Please rate, if it is really helps you. Thank you

Solution :- From the above inforrmation, = 1220, and Up = 0.61 Since sample size is large, so sampling distribut of fw in Ge Jelen è = p=0.61 Of JPCI-P) ORI*(1-0-61) . = 0.01396 1220 ~ = 10.014 option d'is correct Approximately normal Up = 0.61, Op = 0.014.
