###### Question:

The manufacturer of hardness testing equipment uses stool-ball inderters to penetrate metal that is being tested. However, the manufacturer thinks it would be better to use a diamond indenter so that all types of metal can be tested. Because of differences between the two types of indenters, it is suspected that the two methods will produce different hardness readings. The metal specimens to be tested are large enough so that two Indentions can be made. Therefore, the manufacturer ses both indenters on each specimen and compares the hardness readings Construct a 95% confidence interval to judge whether the two indeters resut in different measurements Note: A normal probably plot and boxplot of the data indicate that the differences are approximately normally distributed with no outiers Click the icon to view the datatable Construct a 98% confidence interval to judge whether the two indenters result in different monsurements, where the differences are computed as 'diamond minus tool ball. The lower bounds The upper bounds (Round to the nearest tenth as needed) State the appropriate conclusion. Choose the correct answer below. O There is insufficient evidence to conclude that the two indenters produce different hardness readings O There is sufficient evidence to conclude that the two indenters produce different hardness readings
