Question: The element titanium has five stable occurring isotopes, differing from each other in the number of neutrons an atom contains. If X is the number

The element titanium has five stable occurring isotopes, differing from each other in the number of neutrons an atom contains. If X is the number of neutrons in a randomly chosen titanium atom, the probability mass function of X is given as follows:

х 25 26 p(x) 0.0825 0.0744 0.7372 0.0541 0.0518 27 0.0541 24 0.0518


a. Find μX.

b. Find σX.

25 26 p(x) 0.0825 0.0744 0.7372 0.0541 0.0518 27 0.0541 24 0.0518
