You’re scrolling through Instagram and you notice that a lot of people are posting selfies. This piques yourcuriosity and you want to estimate the percentage of photos on Instagram that are selfies.(a) (5 points) Is there a “ground truth” for the percentage of selfies on Instagram? Why or why not?(b) (5 points) Is it possible to estimate the ground truth percentage of selfies on Instagram?Irrespective of your answer to the previous question, you decide to pull up n = 250 randomly chosenphotos from your friends’ Instagram accounts and find that 32% of these photos are selfies.(c) (15 points) Determine which of the following is an observation, a variable, a sample statistic (valuecalculated based on the observed sample), or a population parameter.• A photo on Instagram.• Whether or not a photo is a selfie.• Percentage of all photos on Instagram that are selfies.• 32%.(d) (5 points) Based on the sample you collected, do you think 32% is a reliable ballpark estimate for theground truth…

All work must be your own. Solutions will be checked for Al usage and plagiarism. Any detected violation will result in a score of 0. Problem Let X and Y be Banach spaces, and let T: X →Y be a bounded linear operator. Consider the following tasks: 1. [Banach Fixed-Point Theorem] a State and prove the Banach Fixed-Point Theorem (Contraction Mapping Theorem). Provide a detailed explanation of how the theorem guarantees the existence of a unique fixed point for a contraction mapping on a complete metric space. b. Let T: X → X be a contraction mapping on X = R² with T(r. u) = (3.). Find the unique fixed point of T. 2. [Duality and the Hahn-Banach Theorem] a.
