Coef means: coefficient. the coef for the constant term (the y intercept) is given the coef for the variable term (the slope) is given
hmm, it appears that they already GIVE you the regression equation where it says: "The regression equation is"
@ganeshie8 if u get a second lmk if u could help me out with this one ><
would it be: 0.92 + 2.06x ?
almost, it says to round to 3 decimal places
you picked the right numbers, you just need to round differently
so like 0.920 + 2.060x ?
look at the table again
the constant is 0.919 and the coefficient is 2.0647, which rounds to 2.065
ok and then for the next question do i just plug in 25 C to get 52.42 or do I use the graph?
use the function, let x = 25
so 52.544 ?
thank you so much @Vocaloid you're the only one who has been able to help me on this one lol. it goes on to ask: the percent of the variation in beak heat loss is explained by the straight-line relationship with temperature is ______. Round your answer to one decimal place. so it would it be 83.6% ?
awesome and then the last one says: Using the information in Figure 4.9, the correlation r between beak heat loss and temperature is ______. Round your answer to 3 decimal places. Is it 4.507??
nope they give you r^2, just take the square root of that to find r
wait which is r^2?
so change it to 0.824 and square root to get 0.908 ?
Thank you so much :)
