The regression equation y = 0.5x + 1.3 approximates the number of hours it takes to arrange a dinner event, y, given the number of people attending, x.
Which statement is true?
For every extra hour taken to make arrangements for an event, the attendance increases by 1.3 people.
For every extra person attending an event, the time it takes to make arrangements increases by 0.5 hour.
For every extra person attending an event, the time it takes to make arrangements increases by 1.3 hours.
For every extra hour taken to make arrangements for an event, the attendance increases by 0.5 people.
NVM
c) For every extra person attending an event, the time it takes to make arrangements increases by 0.5 hour
y is the time
x is nº of people
When x=1 (one person is attending the dinner):
y= 0,5 x 1 +1.3
y= 1.8 hours
When x=2 (two peple are attending the dinner):
y= 0,5 x 2 +1.3
y= 2,3 hours
When x=3 (three people are attending the dinner):
y= 0,5 x 3 +1.3
y= 2,8 hours
the difference between 1.8 and 2.3 h is exactly 0,5 h.
And the difference between 2.3 and 2.8 h is also 0,5 h.
If you continue to increase x, the y will increase 0,5
