PLEASE USE GEOGEBRA IN THIS QUESTION!!

Also use one-tailed test and Ha is suppose to be higher than 0.05

[7] 4. A statistics instructor uses their free time to compose a \"Condence Interval Rap\". The instructor believes this educational rap will help students to study and understand statis- tics. To test the effectiveness of this rap as a study aid, the instructor divides a class of statistics students into two groups, assigning each student to one of the two groups at random. Group A studies for a pop quiz while the \" Condence Interval Rap\" is played on repeat using the class sound system, while group B studies for the pop quiz in silence. Both groups then write the pop quiz in silence, and their grade performance is compared. [3] (a) Use a independent samples ttest to compare the performance of the true groups, using the alternative hypothesis that the rap group should do better. Use a signif- icance threshold of oz = 0.05. State all relevant hypotheses (in symbols) and test statistics / distributions, as well as the pvalue and appropriate conclusion of the test. Sample Statistics: "RAP = 15; ERAP = 55; SRAP = 5 "QUIET = 15, {TEQUIET = 70, SQUIET = 4
