From a population of cereal boxes marked "12 ounces," a sample of 16 boxes is selected and the contents of each box weighed. The sample revealed a mean of 11.7 ounces with a standard deviation of 0.8. Test to see if the mean of the population is at least 12 ounces. Use a 0.05 level of significance. (may use traditional or p-value method)
The following data was randomly drawn from a normal population. At an alpha level of .05, does the mean of the population differ significantly from -150. Use Excel.
Assume that waiting times are approximately normally distributed. Construct a 98% confidence interval for the population mean of waiting times.
Statistics is science of conducting studies to: Solve a system of equations.
