To calculate: The percent of lobsters that weigh more than

Answer to Problem 5ST
The percent of lobsters that weigh more than
Explanation of Solution
Given information:
Themean weight is
Formula used:
The number x is known as standardized value to z where z is provided value of
Calculation:
Consider the provided information that mean weight is
To compute percent of lobsters that weigh more than
Recall that the number x is known as standardized value to z where z is provided value of normal distribution, m is the mean and
Here, zis
Apply it,
The total area under the curve is 1 and standard normal curve is symmetric about y -axis.
The required percent is the area under the curve of standard normal to the right of
Multiply the result by 100, to obtain the answer in percentage form,
Thus, the percent of lobsters that weigh more than
