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>
The correct answer is- Proton
A proton is approximately 2,000 times heavier than an electron. In most cases, atoms have an equal number of protons and electrons. However, because protons are so much heavier than electrons, the electrons do not make a significant contribution to the mass of an atom.
