data; [7 4 3 6 5 5 6 7 6 6 4 6 3 5 5 4 4 6 7 6 0 7 6 8 5 6 6 5 6 5]YOU HAVE ONLY 30 MINUTES !!!!Question 3) Continues probability distribution (15%) The level of electricity follows uniform distribution between 170V and 240V.a) Find expected value and variance (4%)b) What is the probability that level of electricity will be above 200? (4%)c) The standard deviation of electricity is around 20V. Assume some level of electricity which is 1.5 standard deviation above mean what is the probability being below that number? (7%)In all answers show your calculations (Except variance calculation in question 1. But full points will be given to the correct answer). I need well explained answer !!!!
