The empirical distribution of some variable X is given by the following table. (xi are observed values, ni - their frequencies) Xi; 0.5,1,1.5,2,2.5. Ni; 4,6,8,4,2 Find the sample mean value.
Added by Ruhi E.
Step 1
The table lists values of a variable \( X \) and their corresponding frequencies. The values (\( x_i \)) are 0.5, 1, 1.5, 2, 2.5 and their frequencies (\( n_i \)) are 4, 6, 8, 4, 2 respectively. Show more…
