    Distribution of sample means and variances

    Homework Statement Let X1,X2,...,Xn be i.i.d. Normal(μ,σ2) random variables, where the sample size n≥4. For 2≤k≤n-2, we define: Xbar = (1/n)SUM(Xi) from i=1 to n Xbark = (1/k)SUMXi) from i=1 to k Xbarn-k = (1/n-k-1)SUMXi from i=k+1 to n...

    Any energy generation process means mass loss?

    Hello all, Considering that Einstein told us that E=mc2, that means that any energy is generated at a cost of mass loss? to be more specific: When a power plant generates energy by burning gas or coal, a part of the particles in the fuel burned simply disappear and can't be found in the...

    What it means to be a professor

    I'm a little confused as to what it is to be a college science professor. So if you get your PhD, your considered a scientist because you have done your own original research (at a university of course). Now you graduate and apply for jobs. I would assume that someone who is hired into, say...

    PH<pKa means acidic form, but why?

    Lower inertia means it moves faster, right?

    I was working out a conceptual question that asks: if a disk and a hoop of equal mass and radius start from the top of a ramp, are realeased at the same time, and roll without slipping, which one reaches the bottom of the ramp first? Disk: I = 1/2(m)(r^2) Hoop: I = mr^2 So the inertia...

    Hoeffding inequality for the difference of two sample means?

    In W. Hoeffding's 1963 paper* he gives the well known inequality: P(\bar{x}-\mathrm{E}[x_i] \geq t) \leq \exp(-2t^2n) \ \ \ \ \ \ (1), where \bar{x} = \frac{1}{n}\sum_{i=1}^nx_i, x_i\in[0,1]. x_i's are independent. Following this theorem he gives a corollary for the difference of two...

    More alkyl groups you're attached to means you are more energetically

    In alkenes, the more alkyl groups you're attached to means you are more energetically stable, and that we know the reactivity increases as the stability of the intermediate carbocation increases (with tertiary the most stable) I'm puzzled by this relationship, how is it that when it is more...

    MHB Square root in Q(root 2) means its in Z[root 2]

    Let $a,b \in \mathbb{Z}$, and if $a+b\sqrt{2}$ has a square root in $\mathbb{Q}(\sqrt{2})$, then the square root is actually in $\mathbb{Z}[\sqrt{2}]$. Only one approach comes to my mind. Let $r_1, r_2 \in \mathbb{Q}$ such that $a+b\sqrt{2}=(r_1+r_2\sqrt{2})^2$. This gives $a=r_1^2+2r_2^2...

    Proof involving means in continuous distributions

    I recall reading somewhere that the mean value of a continuous variable is situated at a point that acts as a fulcrum about which all other values are considered "weights". In other words, if we define the mean as μ = \int^{∞}_{-∞} x ρ(x) dx (where rho is the probability density) then...

    Unity means just plain regular 1 ?

    "unity" means just plain regular "1"? Im not sure whether this is a physics or math question, but in many physics problems, instead of saying "1", the problem will say "unity", like "the sine of theta is unity" or the "index of refraction is unity". I am assuming "unity" means just plain...

    Exploring Counter-Propagating Waves: Amplitude and Other Possible Scenarios

    I was given an amplitude of a wave and was asked "What is the amplitude of each of the two counter-propagating waves that give rise to this standing wave" So since it says "counter-propagating" that means the waves are stacked on each other? so its really just half the given amplitude.

    Why higher resistance means more heat produced in a circuit

    They say that nichrome is a better heating element as it has a higher resistance. But if I take V=RI then ain't I decrease since R is high, so current is lesser. Thus, resulting in a lower power dissipated as heat? Also, they aq if I use the wrong wires like thin wires, it will cause a lot of...
