- T2.7 Let X be a normal random variable with mean mu = 28 and standard deviation = 4.5. Find the probability P(20 <= X <= 30).(c) In an experiment, the weight of the subatomic particles was measured repeatedly, producing the following values: 45, 47, 43, 54, 38, 45 and 58 mg. By using the statistical method, report the best estimated value of weight of the particles within uncertainty (+1 standard deviation). Where E(wavg-w1) the uncertainty in weight is ow and standard deviation, w = N is the number N-1 of trials.#5 Find the probability
