Question

2. (8 marks) a study was conducted to determine if there was a difference in the driving ability of students from west university and east university by sending a survey to a sample of 100 students at both universities. of the 100 sampled from west university, 17 reported they had been involved in a car accident within the past year. of the 100 randomly sampled students from east university, 25 students reported they had been involved in a car accident within the past year. the minitab output is listed below: sample x n sample p 1 17 100 0.170000 2 25 100 0.250000 difference

Answer 1

The question deals with statistical analysis comparing driving abilities of students from two different universities using a hypothesis test to determine if there is a significant difference in the proportion of reported car accidents.

Step-by-step explanation:

The question concerns a statistical analysis of a survey conducted to evaluate the difference in driving abilities between students from West University and East University. In particular, it looks at the proportion of students involved in car accidents from each university.

To conduct this analysis, one would typically consider setting up a hypothesis test to compare two proportions, using the given sample data to determine if there is a statistically significant difference between the two groups.

In the survey, 17 out of 100 students from West University reported having been involved in an accident, while 25 out of 100 students from East University reported accidents.

The hypothesis test would seek to determine if the proportion difference of 0.08 (0.25 for East University minus 0.17 for West University) is statistically significant, or if it could have occurred by random chance alone.
