A study of voting chose 663 registered voters at random shortly after an election. Of these, 72% said they had voted in the elec
Bingel [31]

Answer:

c) 72% is a statistic and 56% is a parameter.

Step-by-step explanation:

Previous concepts

A statistic or sample statistic "is any quantity computed from values in a sample", for example the sample mean, sample proportion and standard deviation

A parameter is "any numerical quantity that characterizes a given population or some aspect of it".

Solution to the problem

For this case we know that they select a sample of 663 registered voters and the sample proportion from these registered voters is:

\hat p = 0.72 representing the sample proportion of people who voted in the election

They info that they have is that the true proportion before is p =0.52 and that represent a value related to the population.

So on this case the 0.72 represent a statistic since represent the sample and the 0.52 is a value who represent the population for this case is a parameter.

So the correct option is:

c) 72% is a statistic and 56% is a parameter.

The sides of a triangle are in the ratio 3 : 4 : 5. What is the length of each side if the perimeter of the triangle is 90 cm
svet-max [94.6K]
The sides of the triangle are 3x, 4x and 5x

3x + 4x + 5x = 90
12x = 90
x = 90/12
x = 7.5

first side = 3x = 3 * 7.5 = 22.5 cm
second side = 4x = 4 * 7.5 = 30 cm
third side = 5x = 5*7.5 = 37.5 cm
