How much should a healthy Shetland pony weigh? Let x be the age of the pony (in months), and let y be the average weight of the pony (in kilograms).
| x | 3 | 6 | 12 | 16 | 24 |
| y | 60 | 95 | 140 | 156 | 179 |
-Use a calculator to verify that Σx = 61, Σx2 = 1021, Σy = 630, Σy2 = 88,602 and Σxy = 9,222.
Consider that, x is the age of the pony and y is the average weight of the pony.

- The vertical displacement v of a cracked slurry infiltrated fiber concrete member at maximum shear stress is given by v = a + bw, where w is the crack width, and a and b are estimated from data to be a = 2.5 ± 0.1 mm and b = 0.05 ± 0.01. Assume that w = 1.2 ± 0.1 mm.a) Estimate v, and find the uncertainty in the estimate.b) Of the uncertainties in w, a, and b, only one has a non-negligible effect on the uncertainty in v. Which one is it?Consider y=xsin(pi)x over [0,2] Verify the mean value that applies and find all values c satisfying it.With α = .05 and df = 8, the critical values for a two-tailed t-test are t = ±2.306. Assuming all other factors are held constant if the df value were decreased to df = 5, what would happen to the size of the critical regions?
