Question

If you obtained one thousand $95\%$ confidence intervals for a population mean. $\mu$, roughly how many of the intervals would actually contain $\mu$ ?

Step-by-Step Solution

Answer

$950$

Step 1: Given information

For a population mean, you obtained $1,000$, $95\%$ confidence intervals.

Step 2: Calculation

If we obtained one thousand $95\%$ confidence intervals for a population mean $\mu$ roughly $1000\times \frac{95}{100}=950$ intervals would actually contain $\mu$
