Answer 1

Answer #1

If the confidence interval is more, then the width of the interval will be large whereas if the confidence interval is less, then the width is less.

The width increases as the confidence level increases

If it is decreased from 99 to 95 percent, the interval will get narrower.

Option B is the right answer.

Please can you be specific on what does this imply about the interpretation of the given interval. As well as how much would 99% differ from 95% CI. A 95% confidence interval obtained from a sample of 100 outpatients for the true population mean normal mean systolic blood pressure is given by (114 mmHG, 120 mmHG) .

We have sampled n observations from a normal distribution with known standard deviation σ, and constructed a 95% confidence interval for μ. If the confidence level is changed to 99%, which of the following choices is correct? Group of answer choices The confidence interval will become wider. The confidence interval will become narrower. The confidence interval will stay the same. In a particular case, any of these choices may be correct.

1. -/0.2 points BBUnderStat12 9.3.003. My Not For a fixed confidence level, how does the length of the confidence interval for predicted values of y change as the corresponding x values become farther away from x? As x moves farther from X, the confidence interval becomes narrower. As x moves farther from X, the confidence interval becomes wider As x moves farther from X, the confidence interval remains the same. As x moves closer to the confidence interval becomes wider.
