The same computations as above give us in this case a 95% CI running from 0.69 × SD to 1.83 × SD. So even with a sample population of 10, the actual SD can still be almost a factor 2 higher than the sampled SD. For a sample population N = 100, this is down to 0.88 × SD to 1.16 × SD. To be more certain that the sampled SD is close to the ...
In addition, we suppose that the measurements X 1, X 2, X 3 are modeled as normal distribution N(μ,2). Then, T should follow N(μ,2/) and the parameter μ represents the true speed of passing vehicle. In this experiment, the null hypothesis H 0 and the alternative hypothesis H 1 should be H 0: μ=120 against H 1: μ>120.

Achilles would then have to move 5 meters, where the tortoise would move 2.5 meters, and so on. Zeno argued that the tortoise would always remain ahead of Achilles. Similarly, Zeno's dichotomy paradox arises from the supposition that to move a certain distance, one would have to move half of it, then half of the remaining distance, and so on ...
Carter’s funeral is the first for a president since George H.W. Bush’s in 2018, bringing a rare moment of civility to politics as all of the remaining U.S. presidents came together
