Answer:
Step-by-step explanation:
Given that that (X) the amount of time lapsed between consecutive trades on the New York Stock Exchange followed a normal distribution with a mean of 15 seconds.
i.e. X is normal with mean = 15 and unknown std deviation
Given that
i.e. P(
z=-1.475 (from normal table)
Hence
Using this we find P(X>17) =
It so big problem
but you can do it
