Question

Please answer all parts, show every step and formula, (round to five decimal places

Which Method is this? A project manager for a gear manufacturer was tasked to discover the tolerances for a new large disk cutter. So, he went down to the production floor and took a random sample of disks to analyze. The machine was purchased to spec diameters of 35.4 centimeters. He carefully measured each disk on the same tool, recording the following diameters (in cm): 35.5, 35.3, 35.1, 36.4, 35.4, 35.5. a) Define the population parameter in this context. b) Are these quantitative or categorical data? c) Do these data satisfy the necessary conditions? Explain each condition. Show me the numbers, (independence can be skipped)

Answer 1

(a) Population pevamater is usually the characteristic I under study which is of interest bect unteren. So, " diameter sine" is parameter here. 35.4 is claimed value Ich Yes, these are quantitative as these can be measerede on scale and can be ordered ( categorical data cannot be ordered). Study is to check the claim whether now dish cutter has larger radius on diameter against the claim of 35.4 cm diameter, home it is testing of hypothesis. To proceed with testing, we need either assumption Om of normality (not given here are not assumed here) or sample sine 730 (which is not the case here). Ho cely rondom sample doesn't suffice the study, we need either neomelity assumption or take more sample sine.
