Answer:
The correct option is F.
Step-by-step explanation:
A parameter is a single numerical value describing a certain characteristic of the entire population. It is computed using the population values. For example, population mean, population variance, etc.
A statistic is also a numerical value that defines certain characteristic of a sample. It is computed using the sample values. For example, sample mean, sample variance, etc.
Here the mean score for all the 50 students in the midterm Math exam is computed as 88.
This mean value is a parameter because it is computed using the entire population of 50 students in the math class,i.e. all the population values were included in the calculation of mean 88.
Thus, the correct option is F.
The square root of 7 would like between 2 and 3. This is because 2 x 2 is 4's square root and 3 x 3 is nine's square root. Seven is between four and nine.

Answer:
Your table is filled in below.
Step-by-step explanation:
The scale factor is the ratio of image size to original size. In part (d), the image height is "blocks" while the original height is "feet". So, the units of the scale factor are "blocks/ft".
Sometimes a scale factor has units, like this, and sometimes it is expressed as a pure number. A map scale factor might be the pure number ratio 1 : 62500, or it could also be expressed with units as 1 in : 1 mile.*
__
* actually, these are slightly different scales. 1:62500 is about 0.98643 inches per mile.
