Answer #1

ANSWER:

Would a 90% confidence interval for a population mean be narrower or wider than the :

We have to obtained the 90% confidence interval for a population mean be narrower or wider than the corresponding 95% interval is ,

Here ,

  • A 90% Confidence Interval would be narrower than a 95% Confidence Interval.

EXPLANATION:

This presents because the as the precision of the confidence interval increments (i.e, Confidence Interval width reducing), the reliability of an interval containing the actual mean reduces (less of a range to possibly cover the mean).

Therefore,

OPTION (1) is correct answer.(NARROWER)

  • A 90% Confidence Interval would be narrower than a 95% Confidence Interval.

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.
