Answer:
a) 49%
b) 49
Step-by-step explanation:
We have that:
The proportion of adult women in a certain geographical region is approximately 49%.
a) What proportion of women in the sample of 100100 would you expect to see?
The same as the region, that is 49%.
b) How many women, on average, would you expect to find in a sample of that size?
There are 100 people. In the region, the proportion of women is 49%.
So, in a sample of 100 people, you would expect to find 49 women.
Answer:
Step-by-step explanation:
We need to first find out how much 400% of 170 is and then add that increase to the original 170 people.
4(170) = 680 and
680 + 170 = 850 people after 3 years.
