title: Creating dataset with R with normal distribution
body: <p>I was really hoping if you guys could help me with this question.
  I am trying to Create a dataset with 2500 random numbers between (0, 1000) using a normal distribution with mean µ and variance σ2 where µ = 65 and σ2= 10+(6+5) = 21 (therefore SD = sqrt(21)=4.58); </p>
  
  <p>Currently I have tried using :</p>
  
  <pre><code>  N = 2500
    M = 1
    A = matrix(pnorm(1000, mean=65, sd=4.58, lower.tail=TRUE),N,M) 
  </code></pre>
  
  <p>But this doesn't work seem to work. Is there something I'm doing wrong?</p>
  
  <p>Thank you for you help.</p>
