If Z is a random variable having the standard nor–mal distribution, find the probabilities that it will take on a value (a) Greater than 1.14; (b) Greater than –0.36; (c) Between –0.46 and – 0.09; (d) Between ...(a) Use a computer program to find the probability that a random variable having the normal distribution with the mean –1.786 and the standard deviation 1.0416 will assume a value between – 2.159 and 0.5670. (b) ...Check in each case whether the normal approximation to the binomial distribution may be used according to the rule of thumb on page 192. (a) n = 16 and . = 0.20; (b) n = 65 and . = 0.10; (c) n = 120 and . = 0.98. Using the form of the gamma function of Exercise 6.8, we can write And hence Change to polar coordinates to evaluate this double integral, and thus show that (12 ) = v p. In exercise If the probability density of X is given by Find the probability density of Y = X3. Also, plot the graphs of the probability densities of X and Y and indicate the respective areas under the curves that represent P(1/2 < X < ...Post your question
