Answer.

a. Population is the total number of voters in the constituency, that is 10000

b. the parameter is the unknown character of the population, that is 35% of 10000= 3,500

c. Statistics of interest is know character from the sample, that is 40% of 200= 80

d. The two answers are not surprisingly, because the sample is a portion of the population and we expect it to be smaller that the population. Thus, parameter must be bigger than statistics of interest.

d) ii. If another 200 sample was to be taken, we expect to see an increase in a statistics of interest.

Thus my answer, please help by your approval as fast as you can

A small telescope magnifies
WARRIOR [948]

The observatory telescope has 22 times the magnifying power compared to the small telescope.

Data;

  • small telescope = 150 times
  • large telescope = 3300

<h3>Division of Numbers</h3>

To solve this question, we have to divide the large telescope by the small telescope to calculate it's magnifying power.

x = \frac{3300}{150}=22

The magnification of the observatory telescope is 22 times greater or larger than the small telescope.
