Homework Answers
Normal distribution is a continuous distribution and important in statistics and are often used in the natural and social sciences to represent real-valued random variables whose distribution are not known.
The standard normal distribution is a type of normal distribution with mean equal to zero and standard deviation is equal to 1.
The Excel formula calculating the probability value is,
The formula for between probability is as follows:
From the information, observe that the standard normal z score lies between -2 and +2.
The probability that the z score is less than -2 is,
The probability that the z score is less than 2 is,
The calculation of the required probability is,
About 95.45% of the area between 
and 
(Or within 2 standard deviations of the mean)
