Answer:
Step-by-step explanation:
<u>Given function:</u>
<u>Initial population size is when t = 0</u>
<u>The multiple of 1.22 is applied every year, so the ratio of change is:</u>
This is an exponential growth which represents 22% annual growth.
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
