Determine whether the underlined value is a parameter or a statistic. the average score for a class of 28 students taking a calculus midterm exam was modifying 72 % with underline . nothing nothing nothing nothing is the value a parameter or a statistic?
a. the value is a parameter because the class of 28 students nothingis a population.
b. the value is a statistic because the class of 28 students nothingis a population.
c. the value is a parameter because the class of 28 students nothingis a sample.
d. the value is a statistic because the class of 28 students nothingis a sample.

   A. The value is a parameter because the class of 28 students is a population.

Step-by-step explanation:

We know that a parameter is a measure calculated from the whole population where as a statistics is a measure calculated from a sample taken from population.

Given : The average score for a class of 28 students taking a calculus midterm exam was Modifying 72 % with underline .

Since 72% is the proportion of entire population, thus this value is a parameter.

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
