Following are the solution to the given question:
Step-by-step explanation:
Confidence Interval for both the percentage of all x-ray machines
p = the machinery's share is not working:
![\text{Margin of Error} = Z_{(\frac{\alpha}{2})} \times \sqrt{( p \times (1-p)}{n})](https://tex.z-dn.net/?f=%5Ctext%7BMargin%20of%20Error%7D%20%3D%20Z_%7B%28%5Cfrac%7B%5Calpha%7D%7B2%7D%29%7D%20%5Ctimes%20%5Csqrt%7B%28%20p%20%5Ctimes%20%281-p%29%7D%7Bn%7D%29)
Lower
Confidence interval = p - error margin
Upper
Confidence Interval = p + error margin
So,
Confidence Interval ![= ( 0.78 , 0.87 )](https://tex.z-dn.net/?f=%3D%20%28%200.78%20%2C%200.87%20%29)
Answer:
55.5 left over.
Step-by-step explanation:
128/2 = 64
half each week so;
1 whole = two weeks
8 weeks = 8
+ 1 = 8 1/2
so, 64/8.5
is going to be 55.5 left.
