The answer to this question is y = 2/3x + 5
Answer:
: mu1-mu2=0
: mu1-mu2>0
Step-by-step explanation:
Let mu1 be the mean amount of time (in hours) per domestic car repair
and mu2 be the mean amount of time (in hours) per foreign car repair
According to the claim of the automobile technician, the mean amount of time (in hours) per domestic car repair is <em>more than</em> that of foreign cars.
Then <em>null and alternative hypotheses</em> can be stated in <em>symbolic</em> form as
: mu1-mu2=0
: mu1-mu2>0
I do believe that the answer to your question is 60%
6(5y)-y=73 in place of x substitute 5y
30y-y= 73
29y=73
y= 2.52
x= 5(2.52)= 12.6
