The port of South Louisiana, located along miles of the Mississippi River between New Orleans and Baton Rouge, is the largest bulk cargo port in the world. The U. S. Army Corps of Engineers reports that the port handles a mean of million tons of cargo per week (USA Today, September , ). Assume that the number of tons of cargo handled per week is normally distributed with a standard deviation of million tons. a. What is the probability that the port handles less than million tons of cargo per week (to 4 decimals)

a. P(X<5)=0.729

Step-by-step explanation:

The question is incomplete:

"The port of South Louisiana, located along miles of the Mississippi River between New Orleans and Baton Rouge, is the largest bulk cargo port in the world. The U.S. Army Corps of Engineers reports that the port handles a mean of 4.5 million tons of cargo per week. Assume that the number of tons of cargo handled per week is normally distributed with a standard deviation of 0.82 million tons.

a. What is the probability that the port handles less than 5 million tons of cargo per week (to 4 decimals)."

We can solve this using the z-score.

We have a normal distribution with mean 4.5 and standard deviation 0.82.

The z-score for X=5 is:

Then, the probability that X<5 is:

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)

step-by-step explanation:

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
