Converts standard normal random values to lognormals with defined means and variances

`n` |
number of observations |

`mean` |
mean value of the fertility rate |

`var` |
variance of the vital rate (not standard deviation) |

A vector of random lognormal values.

This function could probably be replaced with built-in functions
for the Log Normal Distribution `rlnorm `
