Carmello has done a study to see if exposing kindergartners to an enrichment program increases IQ. His hypothesis is that enrichment programs lead to increased IQ. He found that among students who participated in an enrichment program, average IQ was 103. He used this mean to calculate a p-value based on an assumed population mean of 100 and standard deviation of 15. He got a p-value of .09. Based on this p-value what can he conclude? That enrichment programs lead to a large increase in IQ. That enrichment programs lead to a small increase in IQ. That enrichment programs have no effect on increasing IQ. That the there is a 9% chance that enrichment programs really do increase IQ. That there is a 91% chance that enrichment programs really do increase IQ. That he would get a sample mean as large as or larger than 103 coming out of a population with a mean of 100 and standard deviation of 15, 9% of the time
