- 1244046
- 1818443
- 878337

1818443, 1244046, 878337.

Step-by-step explanation:

In order to put these numbers in descending order, we first need to determine how large they are. We will do this by counting every three zeros, starting from the end:

1244046  --> 1,244,046 - This leaves us with one million / two hundred forty-four thousand / forty six.

1818443 -->  1,818,443 - one million / eight hundred eighteen thousand / four hundred forty-four. This number is larger than the first one (it has larger thousand digits.).

878337​ -->   878,337 - eight hundred seventy-eight thousand / three hundred thirty-seven. This number is the smallest since it is under 1 million.

Therefore the correct order is 1818443, 1244046, 878337.

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247
