The file MidCity Download MidCitycontains data on 128 recent sales in Mid City. For each sale, the file shows the neighborhood (1, 2, or 3) in which the house is located, the number of offers made on the house, the square footage, whether the house is made primarily of brick, the number of bathrooms, the number of bedrooms, and the selling price. Neighborhoods 1 and 2 are more traditional neighborhoods, whereas neighborhood 3 is a newer, more prestigious neighborhood. Conduct a regression analysis to understand, estimate and interpret the square footage of houses in Mid City. Use one Excel spreadsheet labeled P2 to show your work for this problem.   Home Nbhd Offers Sq Ft Brick Bedrooms Bathrooms Price 1 2 2 1790 No 2 2 228600 2 2 3 2030 No 4 2 228400 3 2 1 1740 No 3 2 229600 4 2 3 1980 No 3 2 189400 5 2 3 2130 No 3 3 239600 6 1 2 1780 No 3 2 229200 7 3 3 1830 Yes 3 3 303200 8 3 2 2160 No 4 2 301400 9 2 3 2110 No 4 2 238400 10 2 3 1730 No 3 3 208000 11 2 3 2030…

Neighborhoods 1 and 2 are more traditional neighborhoods, whereas neighborhood 3 is a newer, more prestigious neighborhood. PROBLEM 1: Construct 3 different confidence intervals. Part A) Sort and filter the data from the MidCity file so that you only consider the data from neighborhood 1.  Construct a 99% confidence interval for the square footage of all homes in neighborhood 1.  Make sure you list the specific equations you are using, ALL variables, show ALL work etc., in your report.  You can use Excel to complete all computations. Remember to interpret these confidence intervals in the context of this problem.  Use one Excel spreadsheet…

Example: If a student Vishnu scored 45/50 on exam-1, 92/100 on exam-2 and 55.5/100 on the exam-3, the complete list of data looks like 105, 82, 94.5, 72.5, 92, 91, 52, 86, 100, 96, 98, 109, 96, 90, 92, 55.5 which is the 16 data points Vishnu uses for this project. IMPORTANT: Assume that the complete list of 16 scores as scores of 16 different students in a class and answer the questions below. Q1. What is the sample size of your data? Qualitative Quantitative Neither Discrete Continuous Neither Nominal Ordinal Interval Ratio Q2. Is the data of scores qualitative or quantitative? Q3. Is the data of scores discrete or continuous? Q4. What is the level of measurement for this data?

R Studio       library(poliscidata)       2. (Dataset: nes. Variables: dhsinvolv_message, polknow_combined.) Online political activism is a relatively new phenomenon. In recent years, online social networks like Facebook and Twitter have become part of our everyday experiences and, for many people, a forum for political news and debate. From your own personal experiences, you may have some impressions about who is likely to post political messages online, but our personal perspectives are bound to be limited and incomplete. Let's use the nes dataset to gain a better understanding of who uses social media to promote political ideas. Survey participants were asked whether they had posted a political message on Facebook or Twitter in the last 4 years and the dhsinvolv_message variable recorded their responses.        1. According to the nes dataset, roughly 20% of respondents indicated that they had posted a social media message about politics in the past 4 years. If the probability of an…
