You may need to use the appropriate technology to answer this question. How long it takes paint to dry can have an impact on the production capacity of a business. An auto body & paint business invested in a paint-drying robot to speed up its process. An interesting question is, "Do all paint-drying robots have the same drying time?" To test this, suppose we sample five drying times for each of different brands of paint-drying robots. The time in minutes until the paint was dry enough for a second coat to be applied was recorded. Suppose the following data were obtained. Robot 1 129 137 135 124 140 Robot 2 143 133 142 146 131 Robot 3 Robot 4 133 O Hoi H₁ H₂ H3 #44 H₂H₁ H₂ H3 H4 142 136 137 132 O H₂H₁ = H₂ = H3 H4 H₂: Not all the population means are equal. 151 O Ho: Not all the population means are equal.

An army that overhauls ground mobile radar systems is interested in improving its processes. One problem involves troubleshooting a particular component that has a high failure rate after it has been repaired and reinstalled in the system. The shop floor supervisor believes that having standard work procedures in place will reduce the time required for troubleshooting this component. Time (in minutes) required troubleshooting this component without and with the standard work procedure is recorded for a sample of 19 employess. In order to determine if having a standard work procedure in place reduces troubleshooting time, they should use: a test of two proportions a two-tailed test of two independent means. a one-tailed test of two indepedent means. a two-tailed paired t-test. a one-tailed paired t-test

You are working on the design for a study on the proportion of adults who work remotely in the U.S. The original design sought to limit the margin of error to 0.1 and the new design seeks to limit the margin of error to 0.01. What must be the corresponding change to the minimum sample size? A. It must increase B. Nothing, because the minimum sample size doesn't depend on margin of error C. It must decrease

е. Sample region 6. Question: In a hypothesis test, what does the values of T(0) signify? a. Smallest level of significance for rejection of Null Hypothesis. b. Largest level of significance for rejection of Null Hypothesis. c. Smallest level of significance for acceptance of Null Hypothesis d. Largest level of significance for acceptance of Null Hypothesis 3
using MIL STD 105E for lot of size 100, and using inspection at normal general level ll and acceptance quality level is 2.5% it has been identified plan F with sample size of 20 and the acceptance number is 1. compute the pprobability of accepting lots when the average proportion of defect in the lot is 10%

For a summer job, you were working in the quality control department for a computer company that manufactures computer parts. The specific part that you are to evaluate the quality of is supposed to be 8 micrometers in thickness. You obtained samples of four of these parts manufactured by the day shift and four parts manufactured by the night shift workers. Here are the findings: Day Shift: 7.9, 8.0, 8.2, 8.3 Night Shift: 2, 4, 12, 14 Compute the mean thickness for each shift.Compute the standard deviations for each shift.Which crew is doing a better job? Why?
