Answer:
4
Step-by-step explanation:
The values on the left of the table represent the number of fish caught, and the number of the right of the table represents how many family members caught that amount of fish.
Therefore, the first row means that 0 family members caught 0 fish.
The second row means that 3 family members caught 1 fish.
The third row would mean 1 family member caught 2 fish.
The next row would mean 0 family members caught 3 fish.
And the final row would mean 4 family members caught 4 fish.
The question does not ask for the total amount of fish caught; rather is ask for the maximum number of fish that a single family member caught.
Therefore, the maximum amount of fish that a single family member catches is 4. (And 4 family members did so. But individually, the maximum amount of fish one person caught is 4).
Answer:
The regression line having minimum residuals, actual values closest to estimated regression line values : depicts the most reasonable data model.
Step-by-step explanation:
Regression is a statistical tool depicting cause effect relationship between independent variable(s) (X) , dependent variable. (Y)
Population Regression Function is the conditional expectation of Yi, based on given Xi.
E (Yi / Xi ) =
; where Y's value is based on given X values
Sample Regression Function is estimated relationship between Y & X, based on sample study.
y = b0 + b1x1 ; where y is a estimate of Y, b0 & b1 estimates of
.
In estimating through SRF: there are residuals, i.e differences between actual & estimated values. The most reasonable regression model (regression line) is which minimises the residual values, i.e actual values are closest possible to regression estimated values.
For this matter, classical linear regression model uses 'Ordinary Least Squares' regression, which minimises the residual's squared values.
Answer:
y =
x + 
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 3, - 2) and (x₂, y₂ ) = (5, 4) ← 2 points on the line
m =
=
=
, thus
y =
x + c ← is the partial equation of the line
To find c substitute either of the 2 points into the partial equation
Using (5, 4), then
4 =
+ c ⇒ c = 4 -
= 
y =
x +
← equation of line
