Ten students independently performed an experiment to estimate the value on . Their results were: (a) (b) 3.12, 3.16, 2.94, 3.33, 3.00, 3.11, 3.50, 2.81, 3.02, 3.10 Given that x² = 97.0011, calculate the sample mean, and sample variance, s². Stating any necessary assumption that you make, calculate a 95% confidence interval for based on these data. (c) Estimate the minimum number of results that would be needed if it is required that the width of the resulting 95% confidence interval should be at most 0.02.
