What does the term PR mean in coins?
PR is used in terms of grading coins to designate that the coin is proof. For example, a perfect proof coin would be graded as PR-70. A nearly perfect proof coin might be graded PR-68 or PR-69, etc.
Why some people in Malaysia can have both identity as PR of Singapore and Malaysian?
Anyone can be PR of many countries, PR is not citizenship. It just mean the government of the PR issuing country, grant the person the right to live and work there. So to be a PR of both Singapore and Malaysia is not impossible.
What is the relative frequency of score less than 120 using the 68-95-99.7 rule if a set of test scores is normally distributed with a mean of 100 and a standard deviation of 20?
120 is one standard deviation greater than the mean (z = 1).So you want Pr(z < 1)The probability of a score at most 1 sd away from the mean is 0.68That is Pr(-1 < z < 1) = 0.68So Pr(|z| > 1) = 1 - 0.68 = 0.32then by symmetry,Pr(z > 1) = 1/2*0.32 = 0.16So Pr(z < 1) = 1 - 0.16 = 0.84120 is one standard deviation greater than the mean (z = 1).So you want Pr(z < 1)The probability of a score at most 1 sd away from the mean is 0.68That is Pr(-1 < z < 1) = 0.68So Pr(|z| > 1) = 1 - 0.68 = 0.32then by symmetry,Pr(z > 1) = 1/2*0.32 = 0.16So Pr(z < 1) = 1 - 0.16 = 0.84120 is one standard deviation greater than the mean (z = 1).So you want Pr(z < 1)The probability of a score at most 1 sd away from the mean is 0.68That is Pr(-1 < z < 1) = 0.68So Pr(|z| > 1) = 1 - 0.68 = 0.32then by symmetry,Pr(z > 1) = 1/2*0.32 = 0.16So Pr(z < 1) = 1 - 0.16 = 0.84120 is one standard deviation greater than the mean (z = 1).So you want Pr(z < 1)The probability of a score at most 1 sd away from the mean is 0.68That is Pr(-1 < z < 1) = 0.68So Pr(|z| > 1) = 1 - 0.68 = 0.32then by symmetry,Pr(z > 1) = 1/2*0.32 = 0.16So Pr(z < 1) = 1 - 0.16 = 0.84

What is the 68-95-99.7 rule and could you demonstrate on these problems the mean of 70 and a standard deviation of 15 less than 55 less than 40 less than 85 less than 100 greater than 85?
The rule applies to the normal distribution. For any normal distribution, 68% of the observations lie within 1 standard deviation (SD) either side of the mean that is, between (mean - SD) and (mean + SD); 95% of the observations lie between (mean - 2*SD) and (mean + 2*SD); 99.7% between (mean - 3*SD) and (mean + 3*SD). To find the probability that a normally distributed random variable, with mean = m and SD = s, you calculate its z-score = (X - m)/s and look up the relevant probability value in tables. In doing this, you may have to use the symmetry of the normal distribution or the probability of complementary events (or both). This will depend on what exactly is tabulated. Mean 70, SD = 15 Pr[X < 55] = Pr[Z < (55 - 70)/15] = Pr[Z < -1] = 0.5*(1-0.68) = 0.5*0.32 = 0.16 Pr[X < 40] = Pr[Z < (40 - 70)/15] = Pr[Z < -2] = 0.5*(1-0.95) = 0.5*0.05 = 0.025 Pr[X < 85] = Pr[Z < (85 - 70)/15] = Pr[Z < 1] = 1 - 0.16 = 0.84 Pr[X < 100] = Pr[Z < (100 - 70)/15] = Pr[Z < 2] = 1 - 0.025 = 0.975 Pr[X > 85] = 1 - Pr[X < 85] = 1 - 0.84 = 0.16
