- Calculate coefficient of correlation for the question; marks in economic and marks in statistics as given in the image.In a psychological testing experiment, 25 subjects are selected randomly and their reaction time, in seconds, to a particular stimulus is measured. Past experience suggests that the variance in reaction times to these types of stimuli is 4 sec2 and that the distribution of reaction times is approximately normal. The average time for the subjects is 6.2 seconds. Give an upper 95% bound for the mean reaction time.Suppose that,to test the profitability of name changes in the more recent market (the past 5 years), we analyze the stock prices of a large sample of corporations shortly after they changed names, and we finds that the mean relative increase in stock price was about 0.79% with a standard deviation of 0.12%. Suppose that this mean and standard deviation apply to the population of all companies that changed named during the past five years. Complete the following statements about the distribution of relative increases in stock prices for all companies that changed names. A/ according to chebyshev's theorem, at least ? Of the relative increases in stock price lie between 0.55% and 1.03%? 36%, 56%, 75%, 84% or 89% According to chebyshev's theorem, at least 56% of the relative increases in stock price lie between ? And ? %
