- may you please check my answer, and please dont use AI! may thanks, samarrow_forward4-5.5 A manufacturer of capacitors claims the breakdown voltage has a mean value of at least 1 00 V. A test of nine capacitors yielded breakdown voltages of 97, 1 04, 95, 98, 1 06, 92, 1 1 0, 1 03, and 93 V. a) Find the sample mean. b) Find the sample variance using an unbiased estimate. c) Is the manufacturer's claim valid if a confidence level of 95% is employed?arrow_forwardCourse Name: Calculus with Analytical Geometry-1 Course Code: MATH 132 Do not use Artificial Intelligent Apps Instruction: 1.
