Suppose a simple random sample of size nequals1000 is obtained from a population whose size is Nequals2 comma 000 comma 000 and whose population proportion with a specified characteristic is p equals 0.72 . Complete parts (a) through (c) below. Question content area bottom Part 1 (a) Describe the sampling distribution of ModifyingAbove p with caret. A. Approximately normal, mu Subscript ModifyingAbove p with caretequals0.72 and sigma Subscript ModifyingAbove p with caretalmost equals0.0003 B. Approximately normal, mu Subscript ModifyingAbove p with caretequals0.72 and sigma Subscript ModifyingAbove p with caretalmost equals0.0002 C. Approximately normal, mu Subscript ModifyingAbove p with caretequals0.72 and sigma Subscript ModifyingAbove p with caretalmost equals0.0142 Your answer is correct. Part 2 (b) What is the probability of obtaining xequals750 or more individuals with the characteristic? P(xgreater than or equals750)equals select: 0.0188 0.0188 (Round to four decimal places as needed.) Part 3 (c) What is the probability of obtaining xequals680 or fewer individuals with the characteristic? P(xless than or equals680)equals enter your response here (Round to four decimal places as needed.)
