A part has a specification of 200+/- 30. a gauge R&R study involves 2 operators. 10 parts are measured twice by each operator. Operator 1 measured an average range of 2 and an x-bar bar of 201 for the measurements. Operator 2 measured an average range of 3 and has x bar bar of 205 for the measurements. what is the gauge reproducibility a)2.36 b)3.55 c)1.48 d)2.22

(32%) Create a class of function objects called StartsWith that satisfies the following specification: when initialized with character c, an object of this class behaves as a unary predicate that determines if its string argument starts with c. For example, StartsWith(’a’) is a function object that can be used as a unary predicate to determine if a string starts with an a. So StartsWith(’a’)("alice") would return true but StartsWith(’a’)("bob") would return false. The function objects should return false when called...
