Well I’m guessing it went down by 20% to get to thirty pounds so
30 x 1.2 = $36 original price
Or if it’s lowered by 20% then
30 x 0.8 = $24
The answer is:
545>322
540 <997
We are given with
random samples = 300 batteries
defective samples = 9 batteries
level of significance = 0.1
Using the P-table values and using the given values, we see that the number of defective batteries are really less than 5%
