Math Problem Statement

You intend to estimate a population mean with a confidence interval. You believe the population to have a normal distribution. Your sample size is 4.

While it is an uncommon confidence level, find the critical value that corresponds to a confidence level of 96.3%. (Report answer accurate to three decimal places with appropriate rounding.)

ta/2 = ±±

Solution

The critical value that corresponds to a 96.3% confidence level, assuming a normally distributed population, is approximately ±2.086\pm 2.086.

Would you like more details on this process or have any further questions?

Here are 8 related questions you might find useful:

  1. How do you interpret the critical value in a confidence interval?
  2. What happens to the confidence interval if the sample size is increased?
  3. How do you calculate the margin of error for a confidence interval?
  4. Why is the critical value different for different confidence levels?
  5. How would the critical value change for a smaller confidence level, such as 90%?
  6. What is the difference between using a z-score and a t-score for confidence intervals?
  7. How does the standard error relate to the confidence interval?
  8. Can you use the same critical value for non-normal distributions?

Tip: Always ensure the sample size is adequate when estimating a population mean, as small sample sizes can increase variability in the confidence interval.
