A collection of paired data consists of the number of years that students have studied Spanish and their scores on a Spanish language proficiency test. A computer program was used to obtain the least squares linear regression line and the computer output is shown below. Along with the paired sample data, the program was also given an x value of 2 (years of study) to be used for predicting test score.
Answer the following questions based on the information given above.
For a person who studies for 2 years, obtain the 95% prediction interval and write a statement interpreting the interval.
(31.61, 75.09); we can be 95% confident that the mean test score of all individuals who study 2 years will lie in the interval (31.61, 75.09)
(42.72, 63.98); we can be 95% confident that the mean test score of all individuals who study 2 years will lie in the interval (42.72, 63.98)
(42.72, 63.98); we can be 95% confident that the test score of an individual who studies 2 years will lie in the interval (42.72, 63.98)
(31.61, 75.09); we can be 95% confident that the test score of an individual who studies 2 years will lie in the interval (31.61, 75.09)
