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
2800-2100=700
2800/700=4
4% decrease
The answer is: H0: μ = 76.4 versus Ha: μ > 76.4, where μ = the true mean height of all trucks.
