Calculate. to find the confidence interval. You should have the following output: The confidence interval would be written like: 4.84 < μ < 6.4. The 90% confidence interval for the population mean number of pups is 4.84 pups to 6.41 pups. The calculator also states the sample mean and standard deviation of …

Students use TI-83/84 calculators to conduct a simulation of random samples. The students calculate standard scores with both the population standard deviation and the sample standard deviation. The resulting values are pooled over the entire class to give the simulation a reasonable number of iterations.
