A study was made on the amount of converted sugar in a certain process at various temperatures. The data were coded and recorded as follows: Temperature, x Converted Sugar, y ... 1.0 8.1 1.1 7.8 1.2 8.5 9.8 1.3 1.4 9.5 1.5 8.9 8.6 1.6 1.7 10.2 1.8 9.3 1.9 9.2 10.5 2.0 Answer the following questions: 1. Estimate the linear regression equation: y = a + bx • What is the value of a? Blank 1 • What is the value of b? Blank 2 Remarks: Round off up to 4 decimal places 2. What is the correlation coefficient of the given data? Blank 3 Blank 4 Remarks: Round off up to 4 decimal places 3. What is the strength of the relationship? Blank 5 relationship Options: { Strong, Weak, No } 4. What is the direction of the relationship? Blank 6 Options: { Positive, Negotive }
