Question

good evening! Can someone please answer this, ill give you brainliest and your earning 50 points. Would be very appreciated.

Answer 1

Answer:

• Based on the linear regression equation, the intercept means that for 0 missed classes, the expected test score is 98✓

we know that,

y intercept exist when x = 0

so,

⇢y = -4x +98

⇢y = -4 x 0 +98

⇢y = 98

so , the expected test score is 98

• Based on the linear regression equation, the slope means that for every missed class, the expected tast score decreases by 4 points✓

when x = 0

y = -4(0) +98

when x = 1

y= -4(1) +98 = 94

when x = 2

y= -4(2) +98 = 90

we can see the decresement of 4 points

• Based on the linear regression equation, as the number of days a student misses class increases the expected test score decreases ✓

We can see that the increament in absent days lead to lower scores ( one class = 4 points)

Answer 2

• y=-4x+98

For 0 clases

• y=-0+98=98

Option A is certified as correct

• Here slope is -4

So it decreasing not increasing

Option C is correct

Yes as the missed classes increase expected test decreasing as slope is negative.

Option F is correct
