In the majority of Empirical cases the mean will not be equal to the median, so the event is hardly unusual. If the mean is greater, then the distribution is poitivelt skewed (skewed to the right).
The Normal (or Gaussian) distribution is a symmetrical probability function whose shape is determined by two values: the mean and variance (or standard deviation).According to the law of large numbers, if you take repeated independent samples from any distribution, the means of those samples are distributed approximately normally. The greater the size of each sample, or the greater the number of samples, the more closely the results will match the normal distribution. This characteristic makes the Normal distribution central to statistical theory.

It provides a good approximation to the binomial distribution when np and n(1-p) are greater than 5 for each population.
Scores on the SAT form a normal distribution with a mean of µ = 500 with σ = 100. What is the probability that a randomly selected college applicant will have a score greater than 640?
The statement that the proportion of defective pieces is not less than 0 nor greater than 1.
If n*p is greater than or equal to 5 AND n*q is greater than or equal to 5, you can use a normal distribution as an estimate for the binomial distribution. Recall, n is the number of trials, p is the probability of success of a trial, and q is 1-p.
The Swaroopâ??s index is the proportion of deaths of people aged 50 years and up. The higher the Swaroopâ??s index of a population, the greater the proportion of the deaths who were able to reach the age of 50 years.
NEw bones.
I assume that "public" simply means population. The simple answer is that Greater London has a population of 8.174 million compared with England's population of 53.012 million, representing 15.4%. However, less than half of London's population (44.9%) is "White British". Removing the Welsh, Irish and Scots people, the English proportion of London's population will be considerably smaller. On the other hand a significant proportion of England's population is not English either.
The probability can be calculated by finding the proportion of the interval where the diameter is greater than 7.4 mm. In this case, the proportion of the interval greater than 7.4 mm is (8.5 - 7.4) / (8.5 - 6.8) = 0.55, so the probability is 55%.
The Swaroopâ??s index is the proportion of deaths of people aged 50 years and up. The higher the Swaroopâ??s index of a population, the greater the proportion of the deaths who were able to reach the age of 50 years.
The Gini coefficient is calculated by comparing the distribution of income within a population to a perfectly equal distribution. It ranges from 0 (perfect equality) to 1 (perfect inequality). A higher Gini coefficient indicates greater income inequality within a population.
yes
The answer depends on greater standard deviation that WHAT!
