Explanation Given information: F k 2 − F k − 1 2 . Concept used: a 2 − b 2 = ( a + b ) ( a − b ) F k + F k − 1 = F k + 1 . Proof: The objective is to prove that F k 2 − F k − 1 2 = F k F k + 1 − F k − 1 F k + 1 for all integers k ≥ 1 . For k ≥ 1 consider the left side part of the expression. F k 2 − F k − 1 2 = ( F k − F k − 1 ) ( F k + F k − 1 ) Since a 2 − b 2 = ( a +

Elementary StatisticsBase on the same given data uploaded in module 4, will you conclude that the number of bathroom of houses is a significant factor for house sellprice? I your answer is affirmative, you need to explain how the number of bathroom influences the house price, using a post hoc procedure. (Please treat number of bathrooms as a categorical variable in this analysis)Base on the same given data, conduct an analysis for the variable sellprice to see if sale price is influenced by living area. Summarize your finding including all regular steps (learned in this module) for your method. Also, will you conclude that larger house corresponding to higher price (justify)?Each question need to include a spss or sas output. Instructions: You have to use SAS or SPSS to perform appropriate procedure: ANOVA or Regression based on the project data (provided in the module 4) and research question in the project file. Attach the computer output of all key steps (number) quoted in…

Elementary StatsBase on the given data uploaded in module 4, change the variable sale price into two categories: abovethe mean price or not; and change the living area into two categories: above the median living area ornot ( your two group should have close number of houses in each group). Using the resulting variables,will you conclude that larger house corresponding to higher price?Note: Need computer output, Ho and Ha, P and decision. If p is small, you need to explain what type ofdependency (association) we have using an appropriate pair of percentages. Please include how to use the data in SPSS and interpretation of data.
