The federal Pell grant program gives grants to low income undergraduate students. According to the national post secondary student aid study conducted by the US Department of education in 2008, the average Pell grant award from 2007 to 2008 was $2600. We wonder if the mean amount is different this year for the pool grant recipients at San Jose State University. Suppose that we randomly select 50 Pell grant recipients from San Jose State University. For these 50 students the mean Pell grant award is $2450 with a standard deviation of $600. Let "u" represent The mean amount of Pell grant awards received by San Jose State University Pell grant recipients this year. we test the following hypotheses. The null hypothesis equals 2,600. The alternative hypothesis is not equal to 2,600. What is the t test statistic? What is the P (probability) value
