Consider the following system of equations. 1.75x + 1.25y = 2.75
7x + 5y = 9

What is the solution to the system?

Since 11 ≠ 9, there is no solution.

Since 0 = 0, there are infinitely many solutions.

There is one solution, x = 0 and y = 0.

There are two solutions (11, 0) and (0, 9).

Now, martin can reasonably guess that the standard deviation for the entire population of people at the mall during the time of the survey is $1.50. what is the 95% confidence interval about the sample mean? interpret what this means in the context of the situation where 95 people were surveyed and the sample mean is $8. use the information in this resource to construct the confidence interval.
