Answer:
This is strong evidence that more than 2% get damaged
Step-by-step explanation:
The company goal is to keep the proportion of damaged machines below 2%
One day an inspector randomly checks 66 washers and finds that 6 of them have scratches or dents
So, x = 6
n = 66
Formula :
So, the value of test statistic is 4.114
2) What is the P-value of the test statistic?
So, p value using calculator = .00002
p value < α
So, we accept the alternate hypothesis
So, This is strong evidence that more than 2% get damaged
