Q 24) A Government company claims that an average light bulb lasts 270 days. A researcher randomly selects 18 bulbs for testing. The sampled bulbs last an average of 260 days, with a standard deviation of 90 days. If the CEO's claim were true, what is the probability that 18 randomly selected bulbs would have an average life of no more than 260 day

shwetapardhi/Virtula-Mouse--Final-Year-Project
This project is a hand gesture mouse using OpenCV, Mediapipe and Python. It uses the cam to detect hand gestures and move the mouse accordingly. It also has fuctions to perform left and right clicks, and scroll up and down etc.. Right hand is used to control the mouse and left hand is used to perform other functions such as copy/paste, undo/redo e
