Critical values using t-distribution:
Sample mean :
Standard deviation :
The confidence interval for population means is given by :-
i.e.
Hence, the 95% confidence interval, assuming the times are normally distributed.= (22.12, 27.48)
The given system of equation that is and
has infinite number of solutions.
Option -C.
<u>Solution:</u>
Need to determine number of solution given system of equation has.
Let us first bring the equation in standard form for comparison
To check how many solutions are there for system of equations , we need to compare ratios of
In our case,
As , so given system of equations have infinite number of solutions.
Hence, we can conclude that system has infinite number of solutions.
