X is a random variable which is normally distributed with a mean of 99.01 and a standard deviation of 15.56. Use the Excel function NORMINV to determine the required value of Xo to two decimal places. Give your answer in the form xx.xx. P(X < Xo) = 0.0344
Answer:
X is random variable whuwhis normally distributed with mean 99.01 and standard deviation 15.56. Now we use excel function NORMINV
to determine the required value of X0 such that P(X<X0)=0.0344.
Syntax for NORMINV function:-
NORMINV(probability, mean, standard_dev)
Here,
probability=0.0344 , mean=99.01 , standard_dev=15.56
i.e syntax is,
NORMINV(0.0344, 99.01, 15.56)
And using this function we get the value of X0= 70.69
