With a 95% confidence level, 95% of all sample means will be expected to lie within a confidence interval of ± 1.96 standard errors of the sample mean.

In general, there are three possible alternative hypotheses and rejection regions for the one-sample t -test:
WebbA wide confidence interval indicates that we are less sure and perhaps information needs to be collected from a larger number of people to increase our confidence. Confidence intervals are influenced by the number of people that are being surveyed. Typically, larger surveys will produce estimates with smaller confidence intervals compared to ... Webb1 juli 2024 · Answer. A confidence interval for a population mean with a known standard deviation is based on the fact that the sample means follow an approximately normal distribution. Suppose that our sample has a mean of ˉx = 10, and we have constructed the 90% confidence interval (5, 15) where EBM = 5. To get a 90% confidence interval, we …
