Assume that a sample is used to estimate a population proportion p. Find the 99.9% confidence interval for a sample of size 247 with 85% successes. Enter your answer as a tri-linear inequality using decimals (not percents) accurate to three decimal places

Step-by-step explanation:

The confidence interval for the population proportion is given by:-

, where = sample proportion, n =sample space , z* = critical z-value.

As per given, we have

Critical value for 99.9% confidence = 2.576

The required confidence interval will be:

The required confidence interval:

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
