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
standard normal table
- Search in the table of the standard normal distribution for the
corresponding area of -1 and corresponding area of 0.67
- From the standard normal distribution table we find that
∵ The corresponding area which represents z = -1 is 0.15866
∵ The corresponding area which represents z = 0.67 is 0.74857
- To find the probability between -1 and 0.67 find the difference
between the corresponding areas of -1 and 0.67
∵ z = -1 represented by 0.15866
∵ z = 0.67 represented by 0.74857
∴ The difference of the corresponding areas is:
0.74857 - 0.15866 = 0.58991
∴ The probability that is between -1 and 0.67 is 0.58991
