17. A national manufacturer of ball bearings is experimenting with two different processes for producing precision ball bearings. It is important that the diameters be as close as possible to an industry standard. The output from each process is sampled and the average error from the industry standard is measured in millimeters. The results are shown below. Process A Process B Sample mean 2.0 3.0 Standard deviation 1.0 0.5 Sample size 12 14 The researcher is interested in determining whether...

1.) Two different batteries are being considered for an industrial application. A random sample of 30 of Battery A produces a mean of 16.4 hours of useful voltage with a standard deviation of 3.2 hours. A sample of 30 of Battery B produces a mean of 17.1 hours with a standard deviation of 2.7 hours. The researcher is interested in finding evidence at the .05 level that Battery A has a different average than Battery B. Which of the following...

A researcher is interested in determining whether women show greater affection than men. Affection is measured as a ratio variable- number of hugs given per year. There were 10 men (n1 = 10) in the study and 10 women in the study (n2 = 10). The mean number of hugs for men was 3.5 and the mean number of hugs for women was 5.0. The SS1 for men was 16.5 and the SS2 for women was 28.5. Assume an alpha...

A researcher is interested in the average resting heart rates of elite athletes versus non-elite athletes. The researcher wants to see if the average resting heart rates of elite athletes is lower than average resting heart rates of non-elite athletes. The researcher randomly sampled 45 elite athletes and 60 non-elite athletes. The average resting heart rate of the elite athletes was 46 bpm with a standard deviation of 14 bpm while the average resting heart rate of the non-elite athletes...

4.         A researcher is interested whether number of arrests vary across cities. Two random samples were collected. In city 1, the researcher sampled 185 individuals who had an average of 7.3 arrests with a standard deviation of 2.3 arrests. In city 2, the researcher sampled 160 individuals who had an average of 8.2 arrests with a standard deviation of 2.4 arrests. Test the null hypothesis that the number of arrests does not vary across cities. In so doing, identify: (1)...
