Answer:
The slope of line A equals one-half. The slope of line B equals 2.
Step-by-step explanation:
The equation of Line A is given by : ........... (1)
The equation of Line B is given by : y = 2x - 3 ............. (2)
Those two equations are in slope-intercept form i.e. y = mx + c, where m is the slope of the line.
Now, the slope of line A equals one-half. The slope of line B equals 2.
Therefore, option 1 will be correct. (Answer)
Answer:
the point estimate of the true proportion of employees is 0.401
Step-by-step explanation:
Given data
plan A = ( 0.241 , 0.561 )
to find out
the point estimate for estimating the true proportion of employees who prefer that plan
solution
we know that given data 98% confidence interval for the proportion of employees who prefer plan A: (0.241, 0.561) so point estimate for estimating the true proportion o employees who prefer that plan is p^E
and we can say here
lower limit = = 0.241 ..............1
upper limit = = 0.561 ...............2
now add these two equations 1 and 2
= +
= +
= 0.241 + 0.561
2 p = 0.802
2p = 0.806
p = 0.401
So the point estimate of the true proportion of employees is 0.401
