Answer:
Step-by-step explanation:
Notice how it passed through at exactly (3,2) and (6,4).
By taking the formula for slope:
Substituting this into the slope-intercept form
y = mx + b
where m is the slope of the line and b is the y-intercept.
Since we were not given the y-intercept and the line started or passes through (0,0), we can safely assume that b = 0.
Therefore,
Answer:
The 95% of confidence intervals
(2.84 ,2.99)
Step-by-step explanation:
A random sample of 20 accounting students results in a mean of 2.92 and a standard deviation of 0.16
given small sample size n =20
sample mean x⁻ =2.92
sample standard deviation 'S' =0.16
level of significance ∝ = 0.95
The 95% of confidence intervals
the degrees of freedom γ=n-1 =20-1=19
t-table 2.093
(2.92-0.0748,2.92+0.0748)
(2.84 ,2.99)
Therefore the 95% of confidence intervals
(2.84 ,2.99)
