To calculate a 95% confidence interval for a mean, using a sample of 9 data values, the required t-multiplier, correct to 3 decimal places, would be
Question
Solution 1
To calculate a 95% confidence interval for a mean, you would need to use a t-distribution table because the sample size is small (less than 30).
Step 1: Identify the degrees of freedom (df). The degrees of freedom for a sample is always the sample size (n) minus 1. So in this case, df = 9 - 1 = 8. Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
