Suppose Tatiyana is interested in the relationshipbetween language ability and time spent reading. She120-randomly selects a sample of 30 students from thelocal high school and collects their scores from a을 100-E 80-language aptitude test. She surveys the sample askingeach student how many hours per month he or she60-spends reading.40-Using the sample data, Tatiyana produces a scatterplot20-with reading time on the horizontal axis and languagetest scores on the vertical axis. She develops a least10152025squares regression equation where x is the amount ofReading time in hourstime spent reading during the month and ŷ is thepredicted value of the language test score.ŷ = 3.251x + 31.237Compute the value of ŷ when a student spends 35 hours reading. Give your answer precise to one decimal place. Avoidrounding until the last step.ŷ =pointsIdentify all of the true statements regarding the interpretation of ŷ when x = 35.

i want to solve part 2 and 3 1) show that the two formulae of the geometric mean are equal. 2) If we multiply the data values by a constant (say, c), how this will affect the geometric mean? Use Equation # 2 to prove it, and give an example. 3) If we add a constant (say, d) for all data values, how this will affect the geometric mean? Give an example.
