An English professor assigns letter grades on a test according to the following scheme. A: Top 15% of scores B: Scores below the
lisabon 2012 [21]

Answer:

59 to 66

Step-by-step explanation:

Mean test scores = u = 74.2

Standard Deviation = \sigma = 9.6

According to the given data, following is the range of grades:

Grade A: 85% to 100%

Grade B: 55% to 85%

Grade C: 19% to 55%

Grade D: 6% to 19%

Grade F: 0% to 6%

So, the grade D will be given to the students from 6% to 19% scores. We can convert these percentages to numerical limits using the z scores. First we need to to identify the corresponding z scores of these limits.

6% to 19% in decimal form would be 0.06 to 0.19. Corresponding z score for  0.06 is -1.56 and that for 0.19 is -0.88 (From the z table)

The formula for z score is:

z=\frac{x-u}{\sigma}

For z = -1.56, we get:

-1.56=\frac{x-74.2}{9.6}\\\\ x = 59

For z = -0.88, we get:

-0.88=\frac{x-74.2}{9.6}\\\\ x = 66

Therefore, a numerical limits for a D grade would be from 59 to 66 (rounded to nearest whole numbers)

Anika [276]

Answer:

a. Describing a sample with mean and standard deviation.

Step-by-step explanation:

Statistics can be categorized into descriptive and inferential statistics.

descriptive statistics uses data for descriptions through numerical analysis. It can be further divided in four parts.

  • Measures of Central Tendency ( Mean, Median, and Mode)
  • Measures of Frequency (Count, Percent, Frequency)
  • Measures of Position (Percentile Ranks, Quartile Ranks.)
  • Measures of Dispersion ( Range, Standard Deviation)

Inferential statistics however is based on assumptions and conclusions and generalizations drawn from samples or checks.

options b to d are all examples of inferential statistics while option a is an example of descriptive statistics.
