Step-by-step explanation:
0.2x+0.1(x−0.2x)=105000.2x+0.1(x−0.2x)=10500
0.3x−150x=105000.3x−150x=10500
15x−x50=1050015x−x50=10500
x=10500∗5014=1500∗25=37500
Answer:
1.28
Step-by-step explanation:
Given that a sample of 1500 computer chips revealed that 55% of the chips do not fail in the first 1000 hours of their use. The company's promotional literature states that 53% of the chips do not fail in the first 1000 hours of their use.

(Two tailed test for testing sample proportion with population proportion)
Std error of proportion assuming p = 0.53 is

p difference = 0.02
Z= test statistic = p diff/std error = 1.2775~1.28
