For a second question it says selecting numbers that are statistic. So for question one, our answer is option B. So, so that means that we have for question one, we have this B 20.3 and 1.2. So that means our population mean mu is of course to 20.3 and our population standard deviation sigma, we have that because to 1.2 years. So let's go back to our question in 24 is studying done on all city University of New york to ensure that the main age of students in the first year of of college to be 20.3 years with a standard deviation of 1.3 years. The example of statistics include your sample mean your sample variance, your sample size courtesy. For example, for example, we have the population mean we have the population variance, we have the population size, it's a C while is statistic, it's those details that defines a sample. So a parameter with actually any details or those details that defines a population. So the French questions to select the numbers that are parameters and the second questions is select the numbers that are statistics. In 2014, is studying done on all City University of New York, students showed the mean of students in the first year College to be 20 points three years old with a standard division of 1.2 years in 2018 in 2018, Data collected from example of 100 city University of New York, students showed the middle age of students in the first year of college to be 19.8 years old with a standard division of 15 years.
