Given
n = 196 μ = 71 St.Dev = 42 μ X = 83
Find the Standard Error
S E = σ n = 42 196 = 3
Find the z-score
z = 71 83 3 = -4

A random variable X is normally distributed with μ = 60 and σ = 3. What is the value of 2 numbers a,b so that P ( X = a ) = P ( X = b ).
The solution is a = 60 and b = 65.
However, I do not know how to come up with that answer. As far as I understand P ( X = a ) and P ( X = b ) have to be both 0 since you always have to give a range e.g. P ( a < X ). Moreover if I insert the values 60 and 65 in the formula Z = ( X μ ) / σ than I would end up with 0,1.667 and z-scores 0.5, 0.952 respectively.

In the Z-score formula, can the standard error measurement be used instead of standard deviation?

I'm curious what the phrase "on average" means. Here is an example:
On average, 30 % were further than ___ kilometers away when they had their accident.
Is 30 % a z-score or is it a mean? Transport Canada was investigating accident records to find out how far from their residence people were to when they got into a traffic accident. They took the population of accident records from Ontario and measured the distance the drivers were from home when they had their accident in kilometers (km). The distribution of distances was normally shaped, with µ = 30 kilometers and σ = 8.0 kilometers.

I have learned that z-scores are "Measures of Relative Standing" and that they can be used to compare two scores that are from different normal distributions.

For example if I wanted to compare how I performed

with a 85% in a math class with mean 70 and std dev 15;
and
with a 70% in a english class with mean 50 and std dev 15;

I would use the z-score formula to calculate a relative value for two situation and use it to compare them.

However why is it not enough just to compare each classes with the mean and use this as a basis for comparison? For example

85% -70% = 15%
70% - 50% = 20%
20 > 15 therefore I must have performed better in english

I know this is incorrect but I don't understand why. thx for the help

New questions

i'm seeking out thoughts for a 15-hour mathematical enrichment course in a chinese language high faculty. What (pretty) simple concern would you advocate as a subject for any such course?
historical past/issues:
My students are generally pretty good at math, but many of them have no longer been uncovered to rigorous or summary mathematical reasoning. an amazing topic would be one that could not be impossibly hard for students who have by no means written or study proofs in English.
i have taught this magnificence three times earlier than. (a part of the purpose that i'm posting that is that i have used up all my thoughts!) the primary semester I taught an introductory range theory elegance (which meandered its way toward a proof of quadratic reciprocity, though I think this become in the end too advanced/abstract for some of the students). the second one semester I taught fundamental graph idea and packages (with a focal point on planarity and coloring). The 1/3 semester I taught a class at the Rubik's dice.
the students' math backgrounds are pretty numerous: a number of them take part in contest math competitions, and so are familiar with IMO-fashion techniques, however many aren't. a number of them may additionally realize some calculus, however I cannot assume it. all of them are superb at what in the united states is on occasion termed "pre-calculus": trigonometry, conic sections, systems of linear equations (though, shockingly, no matrices), and the like. They realize what a binomial coefficient is.
So, any ideas? preferably, i'd like to find some thing a bit "sexy" (like the Rubik's cube) -- tries to encourage wide variety theory through cryptography seemed to fall on deaf ears, however being capable of "see" institution idea on the cube became pretty popular.
(Responses specifically welcome from folks who grew up in the percent -- any mathematical subjects you desire were protected within the excessive college curriculum?)
