Question

The area under a particular normal curve between 9 and 11 is 0.7054. A normally distributed variable has the same mean and standard deviation as the parameters for this normal curve. What percentage of all possible observations of the variable lie between 9 and 11​?

Answer 1

Answer:

Area under the normal curve between two values a and b is equal to the pecentage of values of the random variable that lie between a and b

given that the area under the curve (with same mean and standard deviation) between 9 and 11 is 0.7054

so percentage of all possible observations of the variable lie between 11 and 17 is 0.7054*100% = 70.54%
