## theopenstudyowl one year ago I need some help with some Statistics calculator questions! Thankyou!

1. theopenstudyowl

2. Michele_Laino

I think it is 28.26 under the label "Coef"

3. theopenstudyowl

cool!

4. Michele_Laino

here you have this function: $y = B + Ax$

5. theopenstudyowl

ok

6. Michele_Laino

I say 28.3, which is the value of y when x=0

7. theopenstudyowl

ok that make sense!

8. Michele_Laino

I think y=28.26+0.486*x

9. theopenstudyowl

ok cool!

10. Michele_Laino

I think it is the subsequent ratio: $\Large t = \frac{1}{{0.4865}}$

11. KyanTheDoodle

Why is the question post orange if you didn't summon me? This is weird O_O

12. Michele_Laino

namely the last option

13. KyanTheDoodle

OOOOOOOOOHHHHH it's probably because of the whole QH thing.

14. theopenstudyowl

cool

15. theopenstudyowl

thnxs for explaining!

16. Michele_Laino

I see from your table that the requested value of p is p=0.168, under the label "p"

17. Michele_Laino

at first row

18. theopenstudyowl

ok cool sorry for the late reply

19. theopenstudyowl

bazinga

20. Michele_Laino

I think p=0.045 at first row, and last column, or "p" column, second table

21. theopenstudyowl

22. Michele_Laino

I think that we have to use: 30 -2 = 28 degrree of freedom, since we have two parameters, namelythe constants A and B which appears into this formula: y = Ax+B

23. Michele_Laino

sorry for my grammar errors

24. theopenstudyowl

25. Michele_Laino

I think it is 19.96

26. Michele_Laino

27. Michele_Laino

it is 0.2316, since the slope is 0.4865

28. theopenstudyowl

@Michele_Laino sorry for the lare reply, I am currently doing macro right now, here is ht enext question..

29. Michele_Laino

using the table of the "erf" function the requested value is: 1.96

30. theopenstudyowl

ok one more

31. theopenstudyowl

ty

32. Michele_Laino

here I use standard deviation = 0.2316 range of interval= 0.2316*1.96= 0.454 so my answer would be: 0.4865 +/- 0.454

33. Michele_Laino

such answer is not an option of yours!

34. Michele_Laino

try to ask to another QH

35. theopenstudyowl

still thinking lol?

36. Michele_Laino

37. theopenstudyowl

38. Michele_Laino

39. theopenstudyowl
