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
Answer: There are 26 trees which they chop down .
Explanation:
Since we have given that
the number of trees they chop down is given by
Where 'b' denotes number of hours Ben spends chopping,
'c' denotes number of hours Cam spends chopping,
'j' denotes number of hours Justin spends chopping.
Now, we have also given that,
Number of hours Ben spends chopping = 8
Number of hours Cam spends chopping = 3
Number of hours Justin spends chopping = 4
Now, we put the value of all these variable in the above expression ,we'll get
Hence, there are 26 trees which they chop down .
