Answer:
Step-by-step explanation:
Given that population average is 0.8 ampere
Sample size = 9
Sample mean x bar = 1.34 A
Sample std dev s = 0.48
(one tailed test)
Mean difference - 
Std error = 
t test can be used since sigma is not known and sample size small
t statistic = mean diff/std error = 3.5
df = 8
p value = 0.00404
here's your answer

Step-by-step explanation:
So you need to find how much it costs to fix 1 pane.
For that you divide 17.20/8= 2.15
