5 orange + 5 mango = 10
P( mango ) = mango /total = 5/10 = 1/2
Replace
5 orange + 5 mango = 10
P(orange ) = orange /total = 5/10 = 1/2
P(mange, replace, orange) = 1/2 * 1/2 = 1/4

Answer:
173 MRI machines
Step-by-step explanation:
Margin of error E = 0.5
Confidence interval 90% = 1-0.9 = 0.1
Standard deviation = 4 hours
Number of MRI machines needed per day n, = [(z alpha/2 * SD)/E]²
Z alpha/2 = 1.645 at alpha = 0.1
Inputting these values into n we have that
[(1.645*4)/0.5]²
= 13.16²
= 173.18 is approximately equal to 173
The company has to study 173 machines.
