1 )
Assume that a sample is used to estimate a population proportion
p. Find the 99% confidence interval for a sample of size
293 with 82 successes. Enter your answer as an
open-interval (i.e., parentheses) using
decimals (not percents) accurate to three decimal places.
99% C.I. =
Answer should be obtained without any preliminary rounding.
However, the critical value may be rounded to 3 decimal places.
2)
Assume that a sample is used to estimate a population proportion
p. Find the 99.9% confidence interval for a sample of size
86 with 43% successes. Enter your answer as an
open-interval (i.e., parentheses) using
decimals (not percents) accurate to three decimal places.
99.9% C.I. =
Answer should be obtained without any preliminary rounding.
However, the critical value may be rounded to 3 decimal places.
3) Assume that a sample is used to estimate a population proportion p. Find the 98% confidence interval for a sample of size 172 with 38 successes. Enter your answer as a tri-linear inequality using decimals (not percents) accurate to three decimal places.
< p <
Answer should be obtained without any preliminary rounding.
However, the critical value may be rounded to 3 decimal places.
