Number two is A........hope this helps
This is the awnser to the problem
Answer:
Step-by-step explanation:
There are four values 46, 51, 53, 59
we have to draw 2 sampler with replacement
sampler median samler median
46.46 46 53.46 49.5
46.51 48.5 53.51 52
45..53 49.5 53.53 53
46.59 52.5 53.59 56
51.46 48.5 59.46 52.5
51.51 51 59.51 55
51.53 52 59.53 56
51.59 55 59.59 59
sampling distribution of the median
median probability
46 1/16
48.5 2/16
49.5 2/16
52.5 2/16
51 1/16
52 2/16
55 2/16
53 1/16
56 2/16
59 1/16
We know that
<span>An electrician can wire a house in ------------> 20 hours
so
100%----------------> 20 hours
X-------------------> 12 hour
x=12*100/20----> x=60%
that means
</span><span>the apprentice in 12 hours complete the (100-60)----> 40%
</span>the apprentice in 12 hours complete -------> 40%
x hours------------------------------------> 100%
x=100*12/40-----> x=30 hours
the answer is
30 hours
