Re: Easy question, please help to run a function n times

I would use a FOR loop and collect the generated points in a preallocated
vector like,

M=74;
n=88;
T = Range[10000];
For[i=1, i<=10000, i++,
     R= RandomReal[{15,23}];
     T[[i]]= M/(R/n);
];
myMean = Mean[T];

However, this is very much a procedural programming approach. I'm sure the
Mathematica experts helping on this list can provide a more efficient
approach...
