Question
I have posted these questions more than once can anyone actually substitute the right formula
so far no one gave the right answers …..Please help
The following table gives values for a function
N = N(t).
Use your answer to estimate the value of N(18). (Round your answer to one decimal place.)
N = N(t)
10 16.9
20 22.5
30 49.5
40 52.6
50 55.2
60 55.7
70 55.9
The answer is not 20.94 or 20.6 or 21 or 20.76 If someone could provide an answer with the correct formula that would be great
Explanation / Answer
When we regress these values, estimated function is
(you can run a regression in excel using data tab, y values will be n(t) and x values will be 10, 20 , 30.......)
N(t)= 17.02+ 0.67t
for t=18
N(t)= 17.02+ 0.67* 18= 29.185
