question 91

Multiple Choice

A formal hypothesis test is to be conducted using the claim that the mean body temperature is equal to $98.6 ^ { \circ } \mathrm { F }$ . What is the null hypothesis and how is it denoted?

• A) \(H _ { 0 } : p = 98.6 ^ { \circ } \mathrm { F }\)
• B) \(H _ { 0 } : p < 98.6 ^ { \circ } \mathrm { F }\)
• C) \(H _ { 0 } : \mu \neq 98.6 ^ { \circ } \mathrm { F }\)
• D) \(H _ { 0 } : \mu = 98.6 ^ { \circ } \mathrm { F }\)

Waviness

A form of surface irregularity characterized by wave-like deviations from a true flat surface, which can affect the function or aesthetics of the part.

Flaws

Imperfections or defects in a material or structure that can affect its strength, appearance, or functionality.

Roughness Average

A measure of the average deviations of a surface from its geometric ideal form, indicating the surface texture.

Roughness Grade

A classification system for the surface texture of objects, typically measured by the average machined surface roughness.
