Chapter 4, Problem 4.41P

How many independent random measurements of a time-dependent acceleration signal obtained from a vibrating vehicle under fixed operating conditions would lead to a confidence interval about the mean of ±0.5 g, if the standard deviation of the signal is expected to be 1 g?

The "spring-like effect" in a golf club could be determined by measuring the coeffi cient of restitution (the ratio of the outbound velocity to the inbound velocity of a golf ball fired at the clubhead). Twelve randomly selected drivers produced by two clubmakers are tested and the coefficient of restitution measured. The data follow: Club 1: 0.8406, 0.8104, 0.8234, 0.8198, 0.8235, 0.8562, 0.8123, 0.7976, 0.8184, 0.8265, 0.7773, 0.7871 Club 2: 0.8305, 0.7905, 0.8352, 0.8380, 0.8145, 0.8465, 0.8244, 0.8014, 0.8309, 0.8405, 0.8256, 0.8476 Test the hypothesis that both brands of ball have equal mean overall distance. Use a = 0.05 and assume equal variances. Answer the following questions regarding the t-test. 1. How many degrees-of-freedom are there in this problem (needed for finding the critical t- values). 2. What is the absolute values of the critical t-value for this problem? We are using a two- tailed t-test with a significance level of 5%. (use four significant figures) 3. What is…
A temperature measurement system is composed of a sensor and a readout device. The readout device has a claimed accuracy of 0.6 °C with a resolution of 0.1 °C. The sensor has an off-the-shelf limit of error of 0.5 °C. Estimate a design-stage uncertainty in the temperature indicated by this combination. A displacement transducer has the following specifications: Linearity error:±0.25% reading Drift:±0.05%/°C reading Sensitivity error: ±0.25% reading Excitation:  10-25 V Output:  dc 0-5Vdc   Range: 0-5 cm The transducer output is to be indicated on a voltme- ter having a stated accuracy of 0:1% reading with a resolution of 10 μV. The system is to be used at room temperature, which can vary by 10 °C. Estimate an uncertainty in a nominal displacement of 2 cm at the design stage. Assume 95% confidence.
