For the most recent seven years, the U.S. Department of Education reported the following number of bachelor's degrees awardec in computer science: 11,469; 14,738; 8,497; 9,724; 13,434; 6,909; 9,598. What is the annual arithmetic mean number of degrees awarded? Multiple Choice About 10,624 About 18,259 About 8,514 About 14,537
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.
![### Calculation of the Annual Arithmetic Mean Number of Degrees Awarded in Computer Science
For the most recent seven years, the U.S. Department of Education reported the following number of bachelor's degrees awarded in computer science:
- 4,628
- 9,863
- 13,119
- 11,773
- 8,547
- 14,248
- 12,580
**Question:** What is the annual arithmetic mean number of degrees awarded?
#### Options:
1. About 14,593
2. About 10,680
3. About 8,570 (selected)
4. About 18,315
**Explanation:**
To calculate the arithmetic mean, add all the values provided and divide by the number of values.
**Sum of values:**
\[ 4,628 + 9,863 + 13,119 + 11,773 + 8,547 + 14,248 + 12,580 = 74,758 \]
**Number of years:**
\[ 7 \]
**Arithmetic Mean:**
\[ \frac{74,758}{7} \approx 10,680\]
Therefore, the correct answer is approximately **10,680**.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0ab675ce-2e40-481e-8381-32ae8424bad9%2Fcb7750ec-951b-4817-89ce-8bb28753a100%2Fwy9jxaq_processed.png&w=3840&q=75)
