the average IQ of an adult is 100 A research phychologist devised a course to improve IQ's a group of 10 ramdomly cholsen adults took the course and at the end of the course their IQ's were measured. The average IQ score for the class was ramdom sample=110.9. Let x be a ramdom variable that represents the IQ score of an adult who takes the course you may assume that x has a normal distribution with standard deviation=15 does the above sample result provide convincing evidence that adults who take the course have a mean IQ score greater than 100? use level 1% level of significance.
