1. Suppose a sample of students at a major university were given an IQ test, which resulted in a mean of 120 and a standard deviation of 10. If we know that IQs are normally distributed in the population with a mean of 100 and a standard deviation of 16, is there sufficient evidence to suggest that the college students are more intelligent than average?
2.Suppose a single college student were given an IQ test and scored 120. Is there sufficient evidence to indicate that college students are more intelligent than average based on this sample?
