Answer:
a) Parameter
b) Statistic
c) Statistic
d) Parameter
e) Statistic
Step-by-step explanation:
For this case we need to remmber that a parameter describe a population of interest is fixed and not changes , and a statistic is a value that describe the sample size selected and can change between samples.
a. There are 100 senators in the 114th Congress, and 54% of them are Republicans.
The 54% here is a parameter since represent the proportion for all the population of interest on this case.
b. In a 2011 Gallup poll of 1008 adults living in the United States, 11% said they are satisfied with the condition of the national economy.
The 11% here is a statistic since we have a random sample and from this sample we calculate the proportion of interest for this case.
c. A survey of hospital records in 120 hospitals throughout the world shows the mean height of 180 cm for adult males.
The mean height of 180 cm is a statistic since we have a survey not all the population of interest
d. The 59 players on the roster of a championship football team have a mean weight of 248.6 pounds with a standard deviation of 44.6 pounds.
The 44.6 pounds is a parameter since we are interested on all the possible players and we have the info for all of them
e. In a random sample of households in the United States, it is found that 51% of the sampled households have at least one high‑definition television.
The 51% here is a statistic since we have a result from a sample not from the population
Answer:
4037.3264$
Step-by-step explanation:
Total amount of money after 6 years:
A = P x (1 + rate)^time
= 9400 x ( 1 + (6/100)/4)^(6 x 4)
= 13437.3264$
=> Total amount of interest after 6 years:
I = A - P = 13437.3264 - 9400 = 4037.3264$
Answer: The first choice should be correct

Answer:
Graph B
Step-by-step explanation:
Given
Graphs A, B and C
Required
The graph with no solution
Each of the graphs have two parallel lines.
For Graph A
There is a point of intersection between both lines
For Graph B
No visible point of intersection between both lines
For Graph C
Both lines are the same
Since graph B has no point of intersection between the two lines, it has no solution
