To investigate whether there is sexual size dimorphism in a population of painted turtles, you measure shell length for a sample of 10 female and 10 male turtles. You obtain the following results (in mm): Females:98, 103, 103, 105, 109, 123, 123, 133, 133, 133
Males: 93, 94, 96, 101, 102, 103, 104, 106, 107, 112
