Answer:
The probability That is between -1 and 0.67 is 0.58991
Step-by-step explanation:
* Lets explain how to solve it
- A random variable has a standard normal distribution
- Z-scores are -1 and 0.67
- We need to find the probability that is between them by using the
Ā standard normal table
- Search in the table of the standard normal distribution for the
Ā corresponding area of -1 and corresponding area of 0.67
- From the standard normal distribution table we find that
āµ The corresponding area which represents z = -1 is 0.15866
āµ The corresponding area which represents z = 0.67 is 0.74857
- To find the probability between -1 and 0.67 find the difference
Ā between the corresponding areas of -1 and 0.67
āµ z = -1 represented by 0.15866
āµ z = 0.67 represented by 0.74857
ā“ The difference of the corresponding areas is:
Ā Ā 0.74857 - 0.15866 = 0.58991
ā“ The probability that is between -1 and 0.67 is 0.58991
