Conclusion On Changing Role Of Women In Last 25 Years

How shall I write the conclusion of Indian constitution?

The Conclusion of Indian Constitution.It is a very lengthy constitution with 448 Articles grouped into 25 parts and 12 schedules. It is unique in many respects. It is a blend of the many time periods. It attempts a balance between the Fundamental Rights of the individual and the interest of the society and the need for security of the State on the other. This itself is evidence of its resilience, dynamism and growth potential and success

An Economics Question I am having trouble with.?

$100 on Google ensured 5 purchases or 5% hit, let it be 'X' for each purchase (or 5X per 100 ad dollars).

$1000 on ESPN ensured 20 purchases or 2% hit, but it were X+25% for each purchase or 1.25X (or 2*X*1.25=2.5X per 100 ad dollars)

But to have same value as Google, ESPN should be efficient not 2% but 5% out of 100, thus it suppose to be +150% or 250% out of what Google does.

Conclusion: from sales volume point of view change in ad location provided loss (fall in sales volume) but from efficiency point of view change in ad location provided higher efficiency per ad dollar.

Google: 5X per 100 ad dollars.
ESPN: 2.5X per 100 ad dollars.

Were men always the ones who needed companionship from women and not the other way around?

From my last question thread http://answers.yahoo.com/question/index?qid=20111010145144AAHIRII , a few conclusions came about:

1- Women have become far more selective over the past few decades
2- Economic equality has led women to have no financial needs of men
3- Women desired relationships in the past because of certain needs, whether it be financial, immigration, or children.
4- Women are content with social relationships of their multiple peers and associates as opposed to one person

In the past, did women pursue relationships because of a need for sustenance, social pressures, and children (who would be a source of income), or did they pursue relationships because of a need for companionship? Is the reason why women nowadays are more selective because most (or at least a large minority) do not need or desire companionship? In the past, were men the ones who needed companionship more than women, and women would supply them with that in order to receive their needs? Does this explain why so many men are on online dating websites?

I have a few statistics questions I was wondering if you can help me out thanks! Please do a step by step ty!!?

1.A random sample of female college students has a mean height of 64.5 inches, which is greater than the 63-inch mean height of all adult american women.
A. State whether each of the numbers in the above sentence is a parameter or a statistic.
B. Use appropriate notation to describe each number.

2.Just before a presidential election, a national opinion poll increases the size of its weekly random sample from the usual 1500 people to 4000 people.
A. Does the larger random sample reduce the bias of the poll result? Explain.
B. Does it reduce the variability of the result? Explain.

3.Suppose a large candy machine has 15% orange candies. Imagine taking an SRS of 25 candies from the machine and observing the sample proportion p̂ of candies.
A. What is the mean of the sampling distribution p̂? Why?
B. Find the Standard Deviation of the sampling distribution of p̂? Check to see if the 10% condition is met and explain your conclusion.
C. IS the Sampling distribution of p̂ approximately normal? check to see if the normal condition is met and explain your conclusion.
D.If the sample size were 75 rather than 25, how would this change the sampling distribution of p̂? Explain.

4.A grinding machine in an auto parts plant prepares axles with a target diameter μ=40.125 mm. The machine has some variability, so the standard deviation of the diameters is σ= 0.002 mm. The machine operator inspects a random sample of 4 axles each hour for quality control purposes and records the sample mean diameter x̅. Assuming that the process is working properly, what are the mean and standard deviation of the sampling distribution of x̅? Explain.

5.The composite scores of individual students on the ACT college entrance examination in 2009 followed a normal distribution with mean 21.1 and standard deviation 5.1
A. What is the probability that a single student randomly chosen from all those taking the test scores 23 or higher? Show your work.
B. Now take an SRS of 50 students who took the test. What is the probability that the mean score x̅ of these students is 23 or higher? Show your work.
