Hypothesis Testing A psychologist was interested in exploring whether male and female college students have different driving behaviours. The psychologist conducted a survey of a random 34 male college students and a random 29 female college students. She collected the data on the fastest speed driven by the students which is assumed to follow normal distribution with unknown population variance. Furthermore. the variances are assumed to be equal. Here is a descriptive summary of the results of her survey Mean 105.5 km/h 90.9 kmlh Standard deviation 20.1 km/h 12.2 kmlh Assess whether there is sufficient evidence at a = 0.05 level to conclude that the mean of the fastest speed driven by male college students differs from the mean of the fastest speed driven by female college students.
