6.	Prove that the standard deviation of two values x and y of a variable 'x' is half of range
Answer» ANSWER: The standard deviation of the mean (SD) is the most commonly used measure of the spread of values in a distribution. SD is calculated as the square root of the variance (the AVERAGE squared deviation from the mean). Variance in a population is: [x is a value from the population, μ is the mean of all x, n is the number of x in the population, Σ is the summation] Variance is usually estimated from a sample drawn from a population. The unbiased estimate of population variance calculated from a sample is: [xi is the ith observation from a sample of the population, x-bar is the sample mean, n (sample size) -1 is degrees of freedom, Σ is the summation] The spread of a distribution is also referred to as dispersion and variability. All THREE terms mean the extent to which values in a distribution differ from one another. SD is the best measure of spread of an approximately normal distribution. This is not the case when there are extreme values in a distribution or when the distribution is skewed, in these situations interquartile range or semi-interquartile are preferred measures of spread. Interquartile range is the difference between the 25TH and 75th centiles. Semi-interquartile range is half of the difference between the 25th and 75th centiles. For any symmetrical (not skewed) distribution, half of its values will lie one semi-interquartile range either side of the median, i.e. in the interquartile range. When distributions are approximately normal, SD is a better measure of spread because it is less susceptible to sampling fluctuation than (semi-)interquartile range. If a variable y is a linear (y = a + bx) transformation of x then the variance of y is b² times the variance of x and the standard deviation of y is b times the variance of x. The standard error of the mean is the expected value of the standard deviation of means of several samples, this is estimated from a SINGLE sample as: [s is standard deviation of the sample mean, n is the sample size

Choose a number from 1 to 9 such that:AXCX AC = CCC, where the letters A and C stand for different digits.Please tell me shortcut trick of this question

Answer»

Step-by-step EXPLANATION:

the answer will be

A X C X AC = A X C X 10A + C = 100C + 10C + C

= 10A^2C + AC^2 = C (100+10+1)

10A^2 + AC = 111

A ( 10A + C ) = 111

10A + C = 111/A
