![]() Hence, the estimate of yield of maize obtained is ŷ = 146.12 quintal per hectare. Putting a = 53.72 and b = 1.54 in ŷ = a + bx, the regression line of yield of maize (Y) on the rainfall (X) obtained is ŷ = 53.72 + 1.54xĮstimate of yield of maize Y when rainfall x = 60 cm: Putting r = 0.82 S y = 15 and S x = 8, we get Here, n = 7 X = Consumption of fertilizer and Y = Yield of cotton. Obtain the regression line of Y on X and estimate the yield of cotton per hectare if 300 kg fertilizer is used. The following information is obtained from a study to know the effect of use of fertilizer on the yield of cotton: Gujarat Board Textbook Solutions Class 12 Statistics Part 1 Chapter 3 Linear Regression Ex 3.2 Eng.Gujarat Board Statistics Class 12 GSEB Solutions Part 1 Chapter 3 Linear Regression Ex 3.2 Textbook Exercise Questions and Answers.

The necessary calculation relationships are determined and the statistical simulation is carried out for the case of receiving a phase-shift keyed signal. The resulting estimate can be used to control channel selection and the change in the symbol rate, as well as in a number of other tasks. ![]() In this case, for the Gaussian channel (that is the channel in which the interferences can be approximated by Gaussian noise), there is no need to determine the signal and interference levels, and no intervention is required in the operation of the communication system. In the paper, to estimate it, it is proposed to use the variance of the logarithm of the ratio of the amplitudes of the adjacent information symbols. The most important characteristic of a working communication channel is the current signal-to-noise ratio. ![]()
