DIRECTION: Study and analyse the following scenarios below. Choose the most appropriate statistical tool to solve the following problems showing the steps of hypothesis testing, if possible. 1. A query was made to determine the relationship existing between the grades in College Algebra and the grade in Statistics. Random sample of 10 students in a certain class were taken and the following are results of the sampling which were shown in the table below. College 758380 37897892859384 Questions: a) What is the existing relationship between the grades of students in College Algebra and Stalkdies? bi Assumed another student has 94 as grade in College Algebra, what would be his grade in Statistics? 2. The weight of $5 randomly selected students last semester are obtained to test the claim that the mean weight of the students enrolled at our college is greater than 49.7 kilos, Does a sample mean 50 kilos provide evidence to reject the null hypothesis - 49.7 kilos in favour of the alternative hypothesis p - 49.7? Wwe 3 as standard deviation and - 0.05. 3. A class of 20 4" year high school students completed a standardized test in Mathematics with a mean score of 105.8 and a standard deviation of 10.5. At the 0.05 level of significance, do we have sufficient evidence to proclaim this class is superior, if the national mean is 1007 4. Three training methods are employed and then compared if there are differences in the productivity levels of the three groups that are trained. A sample of five trainees each is taken from the three groups. The productivity levels are as follows: 85 At 1% level of significance, do the training methods yield significantly different productivity levels? (and therefore, significantly different training methods)? 5. A student researcher is assigned the task of finding out if the level of education attained by a person depended on the income class to which heshe belonged. He interviews 60 persons. The results are recorded on the table below. In With MAPLD DApieces
