Question

Would a 90% confidence interval calculated from this same sample have been narrower or wider than the given interval? Explain your reasoning. The 90% would be wider since the z

critical value for 90% is larger thanthe z critical value for 95%. The 90% would be wider since the z critical value for 90% is smaller than the z critical value for 95%. The 90% would be narrower since the z critical value for 90% is smaller than the z critical value for 95%. The 90% would be the same since the z critical value for 90% is the same as the z critical value for 95%. The 90% would be narrower since the z critical value for 90% is larger than the z critical value for 95%.
