In an educational institution, the stipends earned by the students in the first year summer internships of the two year post graduate programme are used to decide the amount of financial aid to be given to the students in the second year of the programme. The stipends earned by the students have the following distribution : Stipend earned (in Z) Number of students 0 — 49,999 231 50,000 — 99,999 304 1,00,000 — 1,49,999 400 1,50,000 — 1,99,999 296 2,00,000 — 2,49,999 123 2,50,000 — 2,99,999 68 3,00,000 or more 23 What is the mode value of the stipend earned ? If financial aid is restricted to those students whose stipend earnings are at least 10% lower than the mode value, how many of the applicants qualify?

The​ least-squares regression equation is y=761.7x+13,208 where y is the median income and x is the percentage of 25 years and older with at least a​ bachelor's degree in the region. The scatter diagram indicates a linear relation between the two variables with a correlation coefficient of 0.7483.   Predict the median income of a region in which 20​% of adults 25 years and older have at least a​ bachelor's degree.
