Confidence interval for $\\theta$ when $X_i$s are i. i. d $N(\\theta . . . The statistic to be used is, as usual, $\bar {X}_n\sim N (\theta;\frac {\theta} {n})$ The pivotal quantity is the following $$ \bbox [5px,border:2px solid red] { \frac {\bar {X}_n-\theta} {\sqrt {\theta}}\sqrt {n}\sim \Phi \qquad (1) } $$ So you can find your Confidence interval solving this double inequality with respect to $\theta$ $$-1 64 \leq \frac {\bar {X}_n-\theta} {\sqrt {\theta}}\sqrt
how to solve a Maple problem with three variables? It'd be better suited at www stackoverflow com or www mapleprimes com , but even then you should state exactly what code you issued with a proper description of the goal If you are using Maple's isolve command to try and solve the problems over the integers then state both of those explicitly
algebra precalculus - How do I simplify the following equation . . . Equation of what, exactly? Real numbers? Integers? Complex Numbers? Somewhat relatedly, your "We already know" statement divides by zero under a number of circumstances and you need to make sure to rule these out for the expression to be well-defined (and so do the other expressions, in fact)
the size of Ls cardinals - Mathematics Stack Exchange Gödel's Constructible Universe L is an interesting model of ZF, since it showed the consistency of GCH and AC with ZF's axioms However, that isn't important right now Seeing this Wikipedia page,
algebraic geometry - Computing the Grothendieck group of a spectrum of . . . I've seen your questions on the site often enough to know you've already received this advice, but I'll add my voice to the chorus of those who keep trying It seems that you consistently ask questions about sophisticated formulations of more basic ideas that you don't seem to understand I expect that continuing to ask these questions will end in frustration for you and those who try to help
