The average rate of change in the monthly rate per year is -$0.056 i.e decreases by 0.056 every consecutive year.
Step-by-step explanation:
Step 1; The initial value is $7.69 in 1980 and the final value is $6.13 in 2008.
Difference in values = Final value - initial value = $6.13- $7.69 = -$1.56 (the negative symbol indicates that the cost has gone down with time)
Period between the values =Final year - initial year = 2008 - 1980 = 28 years.
Step 2; To find the rate of change per year, we divide the difference in values in that given period of time by the number of years in that period.
Rate of change per year = Difference in values in that period/ no of years.
= -$1.56 / 28 = -$0.056 (the negative symbol indicates that the cost has gone down with time)
So for every year between 1980 and 2008, the price of the monthly rate for basic able TV reduced by $0.056.

Step-by-step explanation:
Let's differentiate the terms statistic and parameter. Statistic is a branch of mathematics that involves the treatment of various data through collection, preparation, analysis and interpretation. A parameter is a unit of measure which is an element of the system.
Since 78% is the percentage of the whole data, this is a statistic. A parameter, for instance, is the 2,890 readers :)
The answer is A.
I hope you clearly understood my explanation :)
