In the 1970s the weight (in thousand lbs), maximum speed (in knots) and range (in Nautical miles)of various fighter aircraft were recorded. Some of this data is given in Table 9:Weight9.0711.4612.9814.10(1)12.3816.1723.5521.2532.5127.50Table 9Maximum Speed416474590513515601607470546612Range68875290014564798452127123812801450Considering just the data in Table 9, answer the following questions:State the number of variables and the number of observations. Write down the values ofX13 and X21-(11)Calculate the mean vector for the data in Table 9.(111) The correlation between maximum speed and range is roughly the same as thecorrelation between maximum speed and weight. However the covariance betweenmaximum speed and range is many times bigger than the covariance between themaximum speed and weight. Explain why the correlations can be similar but thecovariances can be very different.

There are three variables, Weight Maximum speed Range
