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.

Which is the standard form for this number? (2 x 10) + (5 x 1) + (8 x 1 10,000 )

Me because i don't understand how to do it.: )
