Suppose a population is sampled and the sample mean is 16.8. The sample standard deviation is 6.0 I am to assume the sample is larger than 30) and the sample size is 65.
How do I calculate 95% and 98% confidence intervals.
State which interval wider and why please.
How would I also explain the results of the 95% confidence interval to my boss.
Please help
