Make sure to answer all questions that have not yet been answered Last/First Name (print): PHYS 1440-Section Username ID (XXX9999) WS Analysis A: 1. The voltage difference between the AA and AAA batteries should be quite small. What then might be the difference between them? AXA 2. If we have a resistor labeled brown-black-green-gold, what is the average expected value? Why is it necessary to measure the resistor? Analysis B: 3. What is the average voltage in step 8 of part B? And, when a DC offset is applied, what is the average voltage then? 4. What two values were obtained when calculating the root-mean-square voltage in step 13? How do they compare to the measured value? Which one is correct, and why? (Hint: with an offset Vrms = /DC +

An insurance company wants to know if the average speed at which men drive cars is higher than that of women drivers. the company took a random sample of 27 cars driven by men on a highway and found the mean speed to be 72 miles per hour with a standard deviation of 2.2 miles per hour. another sample of 18 cars driven by women on the same highway gave a mean speed of 68 miles per hour with a standard deviation of 2.5 miles per hour. assume that the speeds at which all men and all women drive cars on this highway are both approximately normally distributed with unknown and unequal population standard deviations.
