The average age in a sample of 190 students at City College is 22. As a result of this sample, it can be concluded that the aver

m_a_m_a [10]

Answer:

The true mean $\mu$ it probably could be larger, smaller, or equal to 22

Step-by-step explanation:

False.

By definition the sample mean is defined as:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}$

For this case the value for the sample size is n =190 and the calculated sample mean is $\bar X=22$ . This value represent the sample and for this case we can't assume that this value represent at all the population as the population mean $\mu$ since we probably have variability from the data of the students at City College.
