a JAR OF PEANUT BUTTER CONTAINS 451G WITH A STANDARD DEVIATION OF 10.2G. FIND THE PROBABILITY THAT A JAR CONTAINS MORE THAN 457G
As per the provided information.
The population mean
is 451 G.
The standard deviation
is 10.2 G.
Let X be the number of grams contained by a jar of peanut butter. So, the random variable X follows normal distribution such that,
Using the standard normal table, the probability that a jar contains more than 475 G can be calculated as:
Therefore, the probability that a jar contains more than 475 G is 0.2776.
