The manufacturer of hardness testing equipment uses steel-ball indenters to penetrate metal that is being tested. However, the manufacturer thinks it wouldbe 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 thatthe two methods will produce different hardness readings. The metal specimens to be tested are large enough so that two indentions can bemade. Therefore, the manufacturer uses both indenters on each specimen and compares the hardness readings. Construct a 95% confidence interval tojudge whether the two indenters result in different measurementsNote: A normal probability plot and boxplot of the data indicate that the differences are approximately normally distributed with no outliersClick the icon to view the data tableConstruct a 95% confidence interval to judge whether the two indenters result in different measurements, where the differences are computed as 'diamondminus steel ballThe lower bound isThe upper bound is(Round to the nearest tenth as needed)Data TableSpecimen 1 2 3 4Steel ball 50 57 61Diamond5687152 56 61 74 69654567 865 516895351 560

The ideal diameter of a rod needed for a machine is 80 mm. The actual diameter can vary from the ideal diameter by 0.009 mm. What range of diameters will be acceptable to the customer without causing the rod to be rejected?
A piece of plywood is composed of five layers. The two outer layers are veneers with thickness 0.50 ± 0.02 mm, and the three inner layers each have thickness 6.25 ± 0.05 mm. Assume the thicknesses of the layers are independent. Estimate the thickness of the plywood and its uncertainty.
The United States Golf Association (USGA) tests all new brands of golf balls to assure that they meet USGA specifications. One of the tests is intended to measure the average distance traveled when the ball is hit by a machine called “Iron Byron”, a name inspired by the swing of the famous golfer Byron Nelson. The USGA proceeded to test with the Iron Byron machine over 250 golf balls of a new type called Ballistic, recording the distance travelled of each one. They then calculated a sample mean and the following 90% confidence interval [335.1; 337.1] (in meters). Based on USGA’s confidence interval they can conclude: HINT: Remember that we build confidence intervals around sample means - not individual observations.

The bottled beverage industry will use robots to fill drinks in bottles containing 1000 ml. There are 2 robot companies (A and B) that offer the industry. Beverage industry managers want the number of drinks that are filled into bottles not to be spilled. Robots are selected that produce the least spillage. To select the robot to be used, experiments were carried out on both robots and observed the amount of drink that spilled from each bottle. If µ1 = the average spill from robot A, µ2 = the average from robot B, then the hypothesis that can be tested from the data:) Ho: µ1- µ2 < 0 dan Ha: µ1- µ2 >= 0 Lainnya (other) Ho: µ1- µ2 <= 0 dan Ha: µ1- µ2 > 0 Ho: µ1- µ2 = 0 dan Ha: µ1- µ2 not equal to 0

I occasionally stop at gas stations that have “free air” and make sure the pressure in my tires is correct. My tires are supposed to have 35 pounds of pressure per square inch. When I connect the hose to my valve the device reads the pressure that is currently in the tire and adds air, if needed, to bring the tire to the pressure that I request. It is important that the pump gauge works properly and does not put in too much or too little air. An inspector checks the air pump twice a year to make sure it is working properly. She connects the air pump to a device that is set to output 35 pounds of pressure and records what the pump gauge displays as the pressure. She repeats this process 10 times. A graph of the data is roughly symmetric with no outliers. The 99% confidence interval for the true mean pressure detected is 33.5 to 34.8 pounds per square inch. He needs to determine if the pump needs to be repaired. What conclusion would you make for a test at the a = 0.01 significance level…
