The problem states: I have 150 quarters. Calculate a confidence interval for the number of coins in my jar. The optimal change is always given. The distribution of coins are discrete uniform.(adsbygoogle = window.adsbygoogle || []).push({});

I have also found that probability of a quarter=.31, probability of a penny=.42, probability of a nickel=.08, and probability of a dime=.1702.

Guidlines suggest to say that q=# of quarters as random variable which comes from population of N=total number of coins as parameter. Use a normal approximation to the appropriate distribution.

Thanks for any help, I'm so stuck
