**Question 6:** A population with a mean ($\mu$) of 85 and a standard deviation ($\sigma$) of 12 is transformed into z-scores. After the transformation, what is the standard deviation for the population of z-scores?**Explanation:**In statistics, z-scores are used to describe a value's position in relation to the mean of a group of values. Z-scores are calculated using the formula:\[ z = \frac{X - \mu}{\sigma} \]Where:- $X$ is the value being transformed,- $\mu$ is the mean of the population,- $\sigma$ is the standard deviation of the population.When a population is transformed into z-scores:- The mean of the z-scores is always 0.- The standard deviation of the z-scores is always 1.Thus, after the transformation, the standard deviation for the population of z-scores is 1.

When the raw scores are transformed to z-scores the mean will be always equal to 0 and the standard…

Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.
