Answer:
Explanation:
The number of defective laptops = 6/145 * 100 as a percent.
The number of defective laptops = 4.13% in a sample of 145
A: False. The percentage should be the same for 290 laptops. The % does not change. The number of defective laptops will change (12)
B: True. It is a reason assertion that about 4% of all laptops will be defective.
C: True. It is not reasonable to assume that only 0.5 laptops will be defective. .5% is too small.
D: True. 10% is too high.
E: False. The variation should not be much.
