Carlos is a very hard-working student who studies every night for at least one hour. His favorite subject is mathematics. He knows that his grade for each marking period is determined by a weight of 50% for all daily work and 50% for major grades, such as, tests, projects and quizzes. He received the following test grades for mathematics during the fourth marking period: 89, 78, 90, 81, 95, and 90. What was his mean mathematics test grade rounded to the nearest whole number? O 90 O 87 O 77 O 93 O O O

Task-1. A professor at a university is wishing to determine whether his introductory statistics class has a good grasp of basic math or not. For this purpose, he chooses six students from his class and gives them a math proficiency test. To have a good grip of basic maths, the professor wants the class score above 70 marks on the test. The scores that the sample of six students gets are 62, 92, 75, 68, 83, and 95. Can the professor say with 90% confidence that the mean score for the whole class on the test would be above 70?
