Answer:
Step-by-step explanation:
Given: The probability of brake pads that come off the production line are considered defective. = 0.2
Therefore, the probability that the brake pads are not defective=1-0.2=0.8
The probability that all 200 pads are not defective P(all 200 non defective)=
Then the probability that at least one brake pad is defective in an order of 200 pads
P(at least one defective)=1-P(all 200 non defective)

Let be the population mean.
Null hypothesis :
Alternative hypothesis :
Since the alternative hypothesis is left tailed, so the test is a left-tailed test.
Sample size : n=5 <30 , so we use t-test.
Test statistic:
Critical t-value for t=
Since, the absolute value of t (1.79) is less than the critical t-value , so we fail to reject the null hypothesis.
Hence, we have sufficient evidence to support the company's claim.
