Take a look at this population pyramid for China. Select the year 1970. What patterns do you notice in the distribution of population across different age-groups? I need help ASAP. Thanks.

It can be noticed that China's population was very young.

Explanation:

In this population pyramid of 1970 about China, it can be noticed the age distribution is much different than nowadays. While in the present China is facing problems because of aging population, in the 1970's it had problem because it had too much young population.

During this period, China's birthrates were very high, and the average lifespan was not really long per say, but nevertheless the population was exponentially growing. Out of fear of this trend, as the population was already huge, the Chinese government implemented laws that forbid the people to have more than one child, except in some cases.

the median of the data is 4.

step-by-step explanation:

the median means the middle number of a given number.

to decide which one is the median, arrange in ascending or descending order. but sometimes, you may find two(2) number in the middle, but it's easy, just add them together and divide by 2.

so,   determine the median of the data. 2, 3, 3, 4, 5, 7, 9

it is already arranged, count 3 times forward and 3 backward and the one left is your answer.

2,3,3,4,5,7,9

our answer is 4.

hope this !
