The mean and standard deviation of random sample of n measurements are equa t0 33. and 3.1, respectively: Find 99% confidence interval for H ifn= 100 Find 99% confidence interval for p ifn= 400_ Find the widths of the confidence intervals found in parts and sample size while holding the confidence coefficient fixed? Wha: the effect on the width of coniidence interval of quadrupling the The 99% confidence interval for | ifn=100 is approximately (Round t0 three decima places as needed:) The 99% confidence interval H ifn=400 is approximately (Round t0 three decimal places as needed ) Choose the correct answer below Quadrupling the sample size while holding the confidence coefficient fixed decreases the width of the coniidence interval by factor 0f 2 Quadrupling the sample size while holding the confidence coefficient fixed increases the width of the confidence interva factor 0i 4. Quadrupling the sample size while holding the confidence coefficient fixed does not affect the width of the confidence interval Quadrupling the sample size while holding the confidence coefficient fixed decreases the width of the coniidence interval by factor 0f 4_ Quadrupling the sample size while holding the confidence coefficient fixed increases the width of the confidence interval by factor 0f 2
