Lucille, Rocio, and Cristina are all taking College Mathematics but from different professors. They all recently took a statistics exam and the exam scores were normally distributed in each of their classes. Lucille's class had an average grade of 85 and the standard deviation was 3. Lucille earned 89.5 on the exam. Rocio's class had an average grade of 83 and the standard deviation was 4. Rocio earned 87.4 on the exam. Cristina's class had an average grade of 76 and the standard deviation was 6. Cristina earned 79.3 on the exam. Since some professors give harder exams than others, these students decided to use statistics to figure out who did the best on their exam.
Two 2017 high school graduates want to compare their results on college entrance exams. Alex scored 1401 on the SAT, and Olivia scored 32 on the ACT. For 2017, the mean SAT score was 1060, and the standard deviation was 195. That same year, the ACT had a mean score of 21.0 and a standard deviation of 5.6. Calculate a z-score for each student, determine which student had the better test score, and explain why.

The local pilots association examined records from this year's census of its members. Tom is a member, and the census shows that he has 4210 hours of flight experience. The census also shows that among all members of the association the mean flight experience is 3095 hours with a standard deviation of 679 hours. Find the z-score of Tom's flight experience relative to the flight experiences of all the members of the pilots association. Round your answer to two decimal places.
The state Government gives grants to low-income undergraduate students. According to the National Postsecondary Student Aid Study conducted by the U.S. Department of Education in 2008, the average Pell grant award for 2007-2008 was $2,600. We wonder if the mean amount is different this year for Pell 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 $2,450 with a standard deviation of $600. Let µ = the mean amount of Pell grant awards received by San Jose State University Pell grant recipients this year. We test the hypotheses: H0: μ = 2,600 , Ha: μ ≠ 2,600. The sample size is greater than 30, so a t-model is a good fit for the sampling distribution. What is the t-test statistic? What is the P-value?
