In this problem, you will see how some estimators are more resilient to corruptions or mistakes in the data than others. Such estimators are referred to as robust . Researchers in a lab observe the following data set {0.5,1.8,−2.3,0.86,0.32}. In reality, these numbers are generated from the standard normal distribution N(0,1) , but as in most statistical problems, this distribution is unknown to the researchers. Their goal is to estimate the mean of this unknown distribution, and they will try two different statistics for doing so: the sample mean and the median. What is the sample mean X¯¯¯¯5 of the data set?

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

step-by-step explanation:

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
