A population has µ = 50 and σ = 5. If 10 points are added to every score in the population, what are the new values for the mean and standard deviation?

Adding a constant to every score increases the mean by the same constant amount. Thus, μ

= 50+10= 60.

Adding a constant to every score has no effect on the standard deviation. σ = 5

Step-by-step explanation:

If a constant value is added to every score in a distribution, the same constant will be added to the mean. similarly, if you subtract a constant from every score, the same constant will be subtracted from the mean.

A;so recall the definition of standard deviation, it measures how each observation is far from its center on average, so if you shift your data by A then, also every observation is shifted by A and then standard deviations stays the same. also think standard deviation as measure of spread not a measure of scale.

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.
