In an Interval Estimate of population mean, I am confused onto why they choose the last one which is Z alpha/2 to look into the confidence levels.. Asked by Danj - Tue Dec 15 01:19:18 2009 - - 1 Answers - 0 Comments A. is a concept related to hypothesis testing. Hypothesis testing is an application of interval estimates in particular confidence intervals. An interval estimate of a population mean ue is constructed by observing a statistic such as x bar and constructing an interval of x bar Z( /2) (standard deviation of x bar) If we use a confidence level of 98 percent for example, we would want a total of 2 percent probability outside of the confidence interval. That 2 percent is the value of . since the normal distribution has two tails, we need for half of the probability to be in the left tail and half of the probability in the right tail . That is the reason for using /2 whose value is 0.01 when confidence level is 98% . … [cont.] Answered by Upward Bound Precalc Tutor - Wed Dec 16 05:22:26 2009 What would be the necessary condition of a parent nucleus to decay into a daughter nucleus and alpha particle? Q. What would be the necessary and sufficient condition of a parent nucleus to decay into a daughter nucleus and alpha particle? The mass are represented as the following: Put in terms of parent nucleus: Mp Daughter nucleus: Md Alpha particle: Ma Speed of light: c Need to think about energy conservation? How much kinetic energy is released too? Asked by Megan - Tue Nov 10 12:59:28 2009 - - 1 Answers - 0 Comments How are the mass number and atomic number of a nucleus affected by alpha and beta emissions?
Q. I need to know the number of the mass and atomic numbers. for example: Gamma has a mass number change of 0 and it has an atomic number change of 0. Now I need to know the same for Alpha and Beta particles. Oh I forgotten that it's important for me to know the penetrating power of alpha,beta and gamma radiation too for Chemistry. Asked by Taylor - Wed Nov 4 20:36:18 2009 - - 1 Answers - 0 Comments A. An alpha particle is a helium atom without electrons (two protons and two neutrons), so when a nucleus experiences alpha decay, the mass decreases by 4, and the atomic number by 2 (loss of two protons). beta particle is just an electron OR a positron, so when a nucleus loses an electron, it gains +1 to atomic number and 0 to mass (beta minus decay) or if it is a positron, it loses -1 to atomic number (beta plus decay).
