Answer:
- z for 184 = -2.2
- P(z < -2.2) ≈ 1.4%
- z for 200 = -0.6
- P(z < -0.6) ≈ 27.4%
- P(184 < x < 200) ≈ 26.0%
Step-by-step explanation:
Z is computed from ...
... z = (x -μ)/σ
Our lower limit for x is 184, so its z-value is ...
... z = (184 -206)/10 = -22/10 = -2.2
Our upper limit for x is 200, so its z-value is ...
... z = (200 -206)/10 = -6/10 = -0.6
A suitable table or probability calculator can tell you ...
... the percent of area associated with z = -2.2 is about 1.4%. That is, about 1.4% of all values lie below z = -2.2.
... the percent of area associated with z = -0.6 is about 27.4%.
The fraction of expenses between $184 and $200 is then calculated to be ...
... 27.4% - 1.4% = 26.0%
the best would be 1.75
Step-by-step explanation:
3/4 turned into a decimal is .75 then you would add the 1 making it 1.75.
Solution :
The term 'literacy rate' provides the ability of a person who is from a definite age group can read or write.
a). does not determine the rate at which the variable explains another, but it explains the amount the amount of variability in one of the variables as explained by the other variable.
b). The slope given provides an expected improvement but it cannot guarantee the improvement. The value may be less or it could be more also.
The regression model provides the prediction and not the actual values.
