50 POINTS .....................

The option (C) Mus. Apt. = -22.26 + 0.4925(IQ score) is correct because the value of slope is 0.4925 and y-intercept is -22.26.

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

$\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2}$

$\rm c = \dfrac{\sum y -m \sum x}{n}$

We have data shown in the picture.

Let's suppose the regression line is:

y = mx + c

Where m is the slope of the regression line and c is the y-intercept of the line.

We can calculate the value of m and c by using the formula.

After calculating, we get:

m = 0.4925

c = -22.26

Mus. Apt. = 0.49253(IQ score) - 22.26

Mus. Apt. = -22.26 + 0.4925(IQ score)

Thus, the option (C) Mus. Apt. = -22.26 + 0.4925(IQ score) is correct because the value of slope is 0.4925 and y-intercept is -22.26.

The mean, median, and mode are all measures of central tendency. The mean is usually the preferred measure of central tendency,

padilas [110]

Answer and explanation:

1. It is commonly referred to as the arithmetic average: the mean measure of central tendency is also referred to as the arithmetic mean or arithmetic average or just average.

It is algebraically defined (that is, there is an equation you can use to calculate its value): the mean can be represented by the algebraic equation

a1+a2+a3...ai/n

2. There can be more than one median where there are an even number of data points and not odd number, in which the two middle number are divided by 2

It can be found when there are undetermined scores: median can be found with undetermined scores

3. It corresponds to an actual score in the data: the mode is an actual value in the data that appears more frequently than other values

There can be more than one: there can be more than one mode(bimodal,trimodal,multimodal) where 2 or more values appear the same number of times
