A company has rolled out a new process for sales people to use. They were able to go back into the company records and pull all sales data from before the roll out. Each sales person when they closed a sale had an average contract of $108 with a standard deviation of $12. During the first month after the roll out, a sample of sales showed the average contract was $116. Which statistical test could be used to see if this was a significant increase in contract size? O z-test O one-sample t-test O independent samples t-test O ANOVA
