In one recent test, police recorded the average speed clocked by cars driving on one busy street close to an elementary school. for a sample of 25 speeds, it was determined that the average amount over the speed limit for the 25 clocked speeds was 11.6 mph with a standard deviation of 8 mph. the histogram of this dataset is shown below. is this sufficient evidence to say that the average speed over the speed limit on this street is different than 10mph? a. check the assumptions and conditions for inference. be sure to take note of the histogram.
