a researcher wishes to test the reaction times of taxi drivers against those of state police officers. The results of the study showed the 10 taxi drivers had a mean of 0.38 seconds with a population standard deviation of 0.02 seconds. the results of the 9 police officers showed a mean of 0.37 seconds with a population standard deviation of 0.01 seconds. Can we conclude with a 0.02 significant level that the taxi drivers had a slower reaction time? Find the p-value.

The department of motor vehicles wants to check whether drivers take a longer time to react after drinking two cans of beer. This was done by selecting a sample of 19 drivers and randomly assigning them to one of two groups. The reaction times (measured in seconds) in an obstacle course are measured for a group of 10 drivers who had no beer. The other group of 9 drivers were given two cans of beer each and their reaction times...

(a) A researcher wishes to test the performance of two paper shredders, the Stanley and the Bosch, designed for professional use. Each of 10 randomly selected volunteers shredded 100 sheets of paper with the Stanley, and then another sample of 10 randomly selected volunteers each shredded 100 sheets with the Bosch. The Stanley took an average of 203 seconds to shred 100 sheets with a standard deviation of 6 seconds. The Bosch took an average of 187 seconds to shred...

A study investigated if cell phone use impacted student drivers' reaction times. There were two groups: 22 students were assigned to the cell phone group while 22 students were assigned to the control group. The experiment measured the response time to traffic lights; for the cell phone group, the mean was 585.7 with a standard deviation of 86.6 and for the control group, the mean was 536.8 with a standard deviation of 66.3. Construct a 90% confidence interval for the...

A researcher is interested in studying the effect of playing video-games on reaction time. Specifically, he thinks that playing a videogame will change reaction times, but he doesn’t know if it will make subjects faster or slower. He collects the following reaction times (in milliseconds) from a sample of 10 subjects before and after playing a video game for one hour. Before Playing a Video Game (T1) After Playing a Video Game (T2) Difference Score (D) = T1-T2 360 374...

1. A social researcher wants to test the hypothesis that people who drink a lot while bowling have higher scores than people who do not drink while they bowl. The researcher studies 50 drinking bowlers and 50 non-drinking bowlers. The average score for drinking bowlers was 142 with a standard deviation of 7.45. The average score for non-drinking bowlers was 134 with a standard deviation of 6.81. In words: What are your conclusions about the null hypothesis? 2. A social...
