Please explain your answer

1 - Which of the following statements is true regarding a 95% confidence interval? Assume numerous large samples are taken from the population.

a. In 95% of all samples, the sample proportion will fall within 2 standard deviations of the mean, which is the true proportion for the population.
b. In 95% of all samples, the true proportion will fall within 2 standard deviations of the sample proportion.
c. If we add and subtract 2 standard deviations to/from the sample proportion, in 95% of all cases we will have captured the true population proportion.
d. All of the above.

Which of the following statements is true? The 95% confidence interval is wider than the 99% confidence interval. The ONLY way to reduce the width of a confidence interval is to reduce the confidence level. The required sample size for a population mean is ONLY dependent on population variance. Given population variance and sampling error, higher confidence level results in larger sample size.

Which of the following statements is true? Group of answer choices 1)The variance of the time taken to complete an activity is equal to (b − a)/6. 2)The critical path is the path with the largest probability of being completed on time. 3)The standard deviation of a project completion time is the sum of the standard deviations for the critical path activities. 4)Three time estimates are necessary so that we can estimate the parameters of the Beta distribution. thanks
