Yes. np > 5 and nq < 5 Yes. np < 5 and nq < 5 No, it is not appropriate to use a normal distribution to approximate the distribution. Yes. np > 5 and nq > 5 Yes. np < 5 and nq < 5 (b) Find a 95% confidence interval for the population proportion of successes p. (Round your answers to three decimal places.) lower limit upper limit (c) Explain the meaning of the confidence interval you computed. O There is a 5% chance that the interval is one of the intervals containing the true proportion. There is a 95% chance that the interval is one of the intervals containing the true proportion.

Consider 204 binomial trials with 72 successes.

Consider 204 binomial trials with 72 successes. (a) Is it appropriate to use a normal distribution to approximate the p distribution? (Select all that apply.) Yes. np > 5 and nq < 5 Yes. np < 5 and nq < 5 No, it is not appropriate to use a normal distribution to approximate the distribution. Yes. np > 5 and nq > 5 Yes. np < 5 and nq < 5 (b) Find a 95% confidence interval for the population proportion of successes p. (Round your answers to three decimal places.) lower limit upper limit (c) Explain the meaning of the confidence interval you computed. O There is a 5% chance that the interval is one of the intervals containing the true proportion. There is a 95% chance that the interval is one of the intervals containing the true proportion.
