A sample of single persons in Towson, Texas, receiving Social Security payments revealed these monthly benefits: $426, $299, $290, $687, $480, $439, and $565. (a) What is the median monthly benefit? (b) Is the mean you computed in (a) a statistic or a parameter? Why?

a) Median Monthly Benefit = $439

b) The mean computed above is a STATISTIC. This is because, the mean of their monthly benefits ($455.14) was calculated from a SAMPLE (which could have been known or random) of single persons in Towson Texas.

Step-by-step explanation:

In the above question, we are given:

: $426, $299, $290, $687, $480, $439, and $565.

a) Median Monthly benefits

First we arrange the monthly benefits from the lowest to the highest

$290, $299, $426, $439, $480, $565, $687

Median Monthly Benefit is the number found in the middle of the Monthly benefits.

We were given 7 monthly benefit

$290, $299, $426,) $439, ($480, $565, $687

The median monthly benefit = $439

(b) Is the mean you computed in (a) a statistic or a parameter? Why?

The Mean Monthly Benefit = Sum of terms/Number of terms

Number of terms = 7

($290 + $299 + $426 + $439 + $480 + $565 + $687)/ 7

= $3186/7

= $455.14285714286

Approximately ≈$455.14

In the question we are asked if the Mean calculated or computed above is a Statistic or a Parameter.

The mean computed above is a STATISTIC. This is because, the mean of their monthly benefits ($455.14) was calculated from a SAMPLE (which could have been known or random) of single persons in Towson Texas.

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
