According to the empirical (68-95-99.7) rule, if a random variable z has a standard normal distribution, then approximately 95% of all values fall between z-scores of -2 and 2. Use the standard normal table or software to determine the precise positive value of z such that 95% of the area under the standard normal density curve is between -z and z. If you use software, you may find this list of manuals useful. Give the positive value of z precise to two decimal places.
Thank you
I. Say true or false. The area under a Probability density function is close to 1. a) b) The mean and variance of normal distribution are 0 and 1 respectively. _The chi-square is a special kind of gamma distribution with a = v/2 and B=3. _The Beta distribution is a special kind of Uniform distribution. _The small sample size imply less error in the estimation of a c) d) e) parameter. _If Variable Y is distributed Chis-square with 10 degrees of freedom, its variance is 5. If the sample size increase the width of the Confidence interval decreases. The standard Beta distribution is defined in the interval a to b. f) g) h) i) _If we can identify the value of the parameters of a gamma distributed function. we can evaluate the mean and variance of the distribution. j) If value of A =20 and B = 30 of a uniform distribution then the mean of the distribution is 28. _Type I error and type II error may increase as the sample size k) decrease. As B increase the power of the test increase. _Type I…
