IQ Scores have a bell-shaped distribution with a mean of 100 and a standard deviation of 15. What percentage of IQ scores are between 70 and 130?
<span>Solution: </span>130 – 100 = 30 which is 2(15). Thus, 130 is 2 standard deviations to the right of the mean. 100 – 70 = 30 which is 2(15). Thus, 70 is 2 standard deviations to the left of the mean. Since 70 to 130 is within 2 standard deviations of the mean, we know that <span>about 95% of the IQ scores would be between 70 and 130.</span>
Answer:
Move the decimal point two places to the right to find the product. To multiply a decimal number by a power of ten (such as 10, 100, 1,000, etc.), count the number of zeros in the power of ten. ... The multiplier 100 has two zeros, so you move the decimal point in 0.054 two places to the right—for a product of 5.4.
Explanation:
According to a different source, this question refers to the text "The Chinese Civil Service Exam System” by Ichisada Miyazaki.
In this text, we learn that the Chinese civil service examination system originated in Ancient China nearly fourteen hundred years ago. Therefore, it is one of the oldest examination systems in the world.
The system was intended to identify the most capable young men in China, and educate them so that they might become part of the government. However, this was a long, difficult and tedious process, and many students and tutors found useful shortcuts to learning. For example, rapid-study methods were devised, such as compiled collections of examination answers.
The Chinese government was aware of such methods, which were strongly condemned. Students who employed them were failed. The government also issued frequent prohibitions of the publication of such materials. However, the success of the business meant that such prohibitions were often unsuccessful.
