An interval of numbers within which the parameter value is believed to fall. A number such that we reject Ho if the p-value is less than or equal to that number. The numerical value obtained from a statistical test. A statistical statement that says a difference between the parameter and a specific value exists or states that there is a difference between two parameters. The error that occurs if you reject the null hypothesis when it is true. 10. The...

Many consumers pay careful attention to stated nutritional
contents on packaged foods when making purchases. It is therefore
important that the information on packages be accurate. A random
sample of n = 12 frozen dinners of a certain type was
selected from production during a particular period, and the
calorie content of each one was determined. (This determination
entails destroying the product, so a census would certainly not be
desirable!) Here are the resulting observations, along with a
boxplot and...
