# Probability calculation for normal distribution

Suppose that scores on a particular test are normally distributed with a mean of 130 and a standard deviation of 19. What is the minimum score needed to be in the top 5% of the scores on the test? Carry your intermediate computations to at least four decimal places, and round your answer to at least one decimal place.

Can you please include spreadsheet to input numbers and compute answer? Thanks
