A metropolitan commission is considering the establishment of limitations on the extent of noise pollution around a local air port. At the present time the noise level per jet take off in one neighboorhood near the airport is approximaelty normally distributed with a mean of 100.7 db and a standard deviation of 6.5 db. Sketch
1 ) what is the probability that a randomly selected jet will generate greater than 109.8 db in this neighboorhood.
2 ) what is the probability that the randomly selected jet will generate a noise level of exactly 100db
can I use can i use possium distribution
u = 6.5db
u= (n a/N = 109.8/100.7
P(100)
