2. A quadratic function has a vertex at (3,-10) and passes through the point (0,8). Which of the following equations best represents the function?
F. y = 2(x + 3)^2 + 8
G. y = 2(x + 3)^2 - 10
H. y = (x - 3)^2 - 10
J. y = 2(x - 3)^2 - 10

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.
