Data;
- small telescope = 150 times
- large telescope = 3300
To solve this question, we have to divide the large telescope by the small telescope to calculate it's magnifying power.
The magnification of the observatory telescope is 22 times greater or larger than the small telescope.

Answer: The estimated value for population mean rating based on these ten sampled ratings is 7.3 .
Step-by-step explanation:
Given : A random sample of size ten produced the following ratings in the computer games rating example in the last lesson:
12, 5, 2, 4, 1, 4, 18, 10, 1, 16.
Let x denotes any value in the above data.
We know that the sample mean is the best estimate to the population mean
.
Sample mean=
Here , n= 10
Therefore , the estimated value for population mean rating based on these ten sampled ratings= 7.3
