4.2 Large Sample Statistics Follow the steps given below to determine the resistance of carbon resistors using a digital multi-meter (DMM) capability of the NI myDAQ. 1. Randomly take 50 $k12 resistors. - Rondomly take 50 ikth resistors 2. Measure the resistance of resistors using the digital multi-meters and record your results in Table 2.3. 3. Calculate sample arithmetic average, deviation, and standard deviation. Use MS Excel to record the measurements and make the computations.

Please answer the following questions: 7. What is the resolution of multi-meter? 8. What is degree of freedom of the measurement? 9. Calculate the 99% confidence interval for the true mean (u). Please show all your work, 10. Calculate the experimental z-statistic. Please show all your work. 2-13

11. Using hypothesis testing, determine whether the sample mean is not equal to the block population's mean (R = Mr) with a confidence level of 99%. Please clearly indicate your choice of the null and alternate hypotheses, and show all your work.
