Story:An E-Commerce portal has collected data regarding the customer activity on the website, app,and purchase portal. The portal management wanted to study the relationship betweencustomers' length of Memberships and the yearly money amount spent by the customer buyingstuff on their portal (The last two columns in the datasheet). Unfortunately, some informationregarding some customers is missing e.g. Length of Membership.A. You have three approaches that needed to be tackled:1) Fill the missing data using 'zeros'2) Fill the missing data using the mean of their column3) Fill the missing data using the median of their columnAfter trying each of them you need to study the effect of your new data proposition onthe correlation between "Length of Membership" and "Yearly Amount SpentB. Using Principal Components Analysis (PCA), Reduce the number of independentvariables to only two(use any library you want for PCA)

The Census Bureau Web site gives several choices for "average income" in its historical income data. In 2006, the median income of American households was $48,201. The mean household income was $66,570. The median income of families was $58,407, and the mean family income was $77,315. The Census Bureau says, “Households consist of all people who occupy a housing unit. The term ‘family’ refers to a group of two or more people related by birth, marriage, or adoption who reside together.” Identify the reason for mean incomes for households being higher than median incomes for households.
If the median house price is $1.9m, does that necessarily mean that half of the houses on the block areworth less than $1.9m and half worth more?

In 2010, the U.S. Congress passed the historic health care reform bill that will provide some type of coverage for the 32 million Americans currently without health care insurance. Just how widespread is the lack of medical coverage? The media claim that the segments of the population most at risk for disease and thus needing healthcare are women, children, the elderly and the poor. The following tables were generated from the U.S. Census Bureau, Current Population Survey, Annual Social and Economic Supplement (2011). The tables report the number of uninsured (in thousands) by sex, by age, and by household income. Is being insured or not dependent on gender? Fill in the degrees of freedom and p-value in the output below and draw a clear conclusion indicating which gender is more at risk of not being insured if there is a significant difference.
