An article reports the following data on yield (y), mean temperature over the period between date of coming into hops and date o

enot [183]

Answer:

$y = 415.113 -6.593 x_1 -4.504 x_2$

Step-by-step explanation:

Given

$x_1: 16.7\ 17.4\ 18.4\ 16.8\ 18.9\ 17.1\ 17.3\ 18.2\ 21.3\ 21.2\ 20.7\ 18.5$

$x_2: 30\ 42\ 47\ 47\ 43\ 41\ 48\ 44\ 43\ 50\ 56\ 60$

$y: 210\ 110\ 103\ 103\ 91\ 76\ 73\ 70\ 68\ 53\ 45\ 31$

Required

Use R code to determine the regression equation

$y = b_o + b_1x_1 + b_2x_2$

First, write the following code in a R program

$x1$

$x2$

$y$

$mod$ ~ $x1+x2)\\$

$summary(mod)$

Next, run the program

See attachment for program and output

From the output, go to coefficients:

Check Estimate Std. column, you have the following:

$(Intercept) = 415.113$

$x_1 = -6.593$

$x_2 = -4.504$

$y = b_o + b_1x_1 + b_2x_2$ implies that:

$b_o \to$ Intercept

$b_1 \to x_1$

$b_2 \to x_2$

Hence, the least square regression equation is:

$y = 415.113 -6.593 x_1 -4.504 x_2$
