Step-by-step explanation:
From the question we are told that
The population mean is
The standard deviation is
From the question we are told that the score follow a normal distribution
i.e
The proportion of score in the top 10% is mathematically
Where x is the minimum score required to be in the top 10%
Now the
So
So
So the critical value of 0.10 from the normal distribution table is
So
Answer:
Step-by-step explanation:
In order to solve this exercise it is important to remember the multiplication of signs. Notice that:
In this case you have the following expression given in the exercise:
Where the variable is "j".
When you multiply signs, you get:
Now you need to identify that like terms and then you need to add them (or combine them). So, applying this procedure you get that the simplified form of the expression is the shown below:
As you can observe, you get a 2nd degree binomial.
