Question 1123119: Trading volume on the New York Stock Exchange has been growing in recent years.
For the first 4 months of 2005, the daily average volume was 646 million shares.
The probability distribution of daily volume is approximately normal with a
standard deviation of 100 million shares.
-What is the probability trading volume will be less than 550 million shares?
-What percentage of the time does the trading volume exceed 710 million
shares?
You can put this solution on YOUR website! z=(x-mean)/sd
z<(550-646)/100
z<-0.96 and probability is 0.1685
z>(710-646)/100 or >0.64; 0.2611 probability or 26.11%
