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.

Answer:
4x+y add like terms ... -5+9=4 and -y(or -1)+2y=y
(3*2)(10^2 * 10^3) = 6*10^5
C. Phonograph were inferior in sound quality.
Step-by-step explanation:
Researches have shown that plants respond to the sounds of their pollinator.
Some plants begin to produce a greater amount of nectar and some begin to vibrate to attract the attention of the pollinators towards them.
Greater the intensity of the sound of the pollinator, the faster the reaction will be.
Phonographs have a sound of lower intensity when compared to the intensity of sound produced by the radio.
Thus the radio was better than the phonograph in encouraging the concept of cross-pollination.
