Question “Find the area of the indicated region under the standard normal curve Click here to view…”
Answer
1]
The area between z=0 and z=1.4 under the standard curve =P( z=1.4 ) -P( z=0 )
= 0.9192 – 0.5000
These values are taken from the given probability table = 0.4192
2]
Normally, the waiting time for a heart-transplant is distributed with a mean of 203 and a standard deviation = 25.2
A] The 5th percentile is the waiting time = 161.55 nearest integer = 162 Days
Using Excel command “=NORMINV(0.05,203,25.2)”, we get 161.55
b] The waiting time for the 3rd Quartile = 219.99 Nearest integer = 220 Days
Using Excel command “=NORMINV(0.75,203,25.2)”, we get 219.99
Conclusion
Above is the solution for “Find the area of the indicated region under the standard normal curve Click here to view…“. We hope that you find a good answer and gain the knowledge about this topic of math.
