Q2. [1 mark] I measure my bike tire pressure at noon, at 1 PM and at 2 PM and the tire pressures are recorded at the right. I know that this ought to be an exponentially decay process but my measuring gauge is a bit hard to read. Provide a good estimate of the half-life h of the process, that is, the time for the P-values to be cut in half. t P 0 400 1 300 2 240
