Answer:
For this case we have information from a sample of n =20 times of temperatures of the oven
The parameter of interest is population temperature mean of the oven
And the statistic is calculated with this formula:
With n = 20 and represent the mean temperature of the oven
The correct option for this case is:
mu = the true mean temperature of the oven xbar = the true mean temperature of the oven
Step-by-step explanation:
Previous concepts
Parameter represent a property of a population and is calculated with the information of all the populatio. Some examples are the population mean and deviation
Statistic represent a propoerty of a sample and are used used in order to describe the population parameters, since represent estimators of the real parameters.
