- Find the uniform distribution of the continuous type on the interval (b, c)that has the same mean and the same variance as those of a chi-square distributionwith 8 degrees of freedom. That is, find b and c.Suppose X has a continuous uniform distribution over the interval -1,1. Determine the variance. Round your answers to 3 decimal places.TRUE OR FALSE The central limit theorem implies that sampling with a sufficiently large sample size taken from the population gives a good estimate of the parameters of the population.
- Derive the mean and variance of discrete uniform distribution. Show your complete solutions.The t distributions _________________ always have a standard deviation which is smaller than the standard deviation of the standard normal distribution (the normal distribution of z-scores). are positively-skewed distributions that contain only positive values. are a family of distributions that differ from one another in their means, but not in their variances. Have a mean of zero and a standard deviation that depends on the degrees of freedom.The marginal distribution of Y, that is fY(y)
- Find the z score that has 66.3% of the distributions area to its right. (Round to 2 decimal places)I want to ask how do we know when we need to use the continuity correction like the second image and when will we use the normal distribution like the 1st image? Thank youfind the z-score that has 30.5% of the distributions area to its left.
