Question: Using the 100 random observations, assume they're a sample, then produce an estimate of the population mean and produce 90%, 95%, and 99% confidence intervals
Using the 100 random observations, assume they're a sample, then produce an estimate of the population mean and produce 90%, 95%, and 99% confidence intervals for this population mean. Assume this is a "large sample" and use critical values from a z-table.
