Svga monitors manufactured by tsi electronics have life spans that have a normal distribution with a variance of 1,000,000 and a mean of 19000 hours is a monitor is selected at random what is the probability that the life span will be more than 19800

Variance = 1,000,000

Standard deviation = sqrt(variance) = 1000

Prob ( lifespan > 19800 ) = 1 - Normcdf ( 19800, mean, sd) = 1- Normcdf (19800,19000,1000) = 1-0.788 = 0.212


Hope this helped!
