Question 2(1 point) A student measures the diameter of a disk fifteen times with a ruler that has a smallest division of 1 mm. The average of the 15 measurements is 17.04667 cm and the sample standard deviation is 5.595063x10"3 cm. The correctly rounded-off uncertainty (don't use scientific notation) is rounded off value is A cm and the correctly A/ cm.

The diameter of a spindle in a small motor is supposed to be 4.5 millimeters (mm) with a standard deviation of 0.14 mm. If the spindle is either too small or too large, the motor will not work properly. The manufacturer measures the diameter in a sample of 17 spindles to determine whether the mean diameter has moved away from the required measurement. Suppose the sample has an average diameter of 4.41 mm. Ho: Ha:

The following data were obtained in order to determine the density of a cylindrical metal bar. Height (cm): 6.50 (Trial 1), 6.45 (Trial 2), 6.44 (Trial 3); Diameter (cm): 1.25 (Trial 1), 1.26 (Trial 2), 1.22 (Trial 3); Mass (g): 46.683 (Trial 1), 46.332 (Trial 2), 47.014 (Trial 3). Calculate the percent relative average deviation of the measurements.

Kane (1986) discusses the concentricity of an engine oil seal groove. Concentric- ity measures the cross-sectional coaxial relationship of two cylindrical features In this case, he studies the concentricity of an oil seal groove and a base cylin der in the interior of the groove. He measures the concentricity as a positive deviation using a dial indicator gauge. Historically, this process has produced an average concentricity of 5.6 with a standard deviation of 0.7. To monitor this process, he periodically...

Consider the following data from a repeated-measures design. You want to use a repeated-measures t test to test the null hypothesis H_0: mu_D = 0 (the null hypothesis states that the mean difference for the general population is zero). The data consist of five observations, each with two measurements, A and B, taken before and after a treatment. Assume the population of the differences in these measurements are normally distributed. Complete the following table by calculating the differences and the...
