Should I use a certain table for this question or should I use a special formula. A random value has a normal distribution with the mean 102.9 and the standard deviation 4.7. What are the probabilities that this random variable will also take on a value
a. Less than 110.1;
b. Greater than 95.6;
c. Between 104.5 and 105.9;
d. Between 98.7 and 150?
I have worked so far by finding the z value and im going on to find it through the table.
