For the cultivation of a cereal, an amount of fertilizer x is applied in Kgs, per unit area and the quantity y of tons of production is obtained. The following data is available:

x 99 100 101 102 103 104 105 106

y 2.1 2.8 7.2. 9.9 9.3 13.6 14.7 17.1

Do the test: H_0: β1 = 0 VS H_1: β1 ≠ 0 . Use α = 0.005.

Make a confidence interval (α = 0.005) for β1.

What would be a prediction interval for future production if x_h = 101 is used? Use 1 − α = 1−0.005

A generous amount of gel is applied to the surface of the window of an ultrasound probe prior to its use. The window is made of a polycarbonate material of density ρ = 1200 kg/m3, thermal conductivity k = 0.2 W/m · K, and specific heat cp = 1200 J/kg · K. The probe is initially at a temperature of Ti = 20°C. To ensure that the gel remains adhered to the probe until the probe is brought into contact...
