9. Intermediate Statistics with Python

Activity 9.01: Standardized Test Performance

Solution:

1. We are going to use the t-confidence interval function that we created earlier to calculate a 95% confidence interval. I have recreated it here for completeness:

   # We will use the T-Confidence Interval Function 
   # we wrote earlier in the Chapter
   print("For Math:")
   t_confidence_interval(list(data['Math']),0.95)
   print("For Reading:")
   t_confidence_interval(list(data['Reading']),0.95)
   print("For Science:")
   t_confidence_interval(list(data['Science']),0.95)

   The output for this code should be the following:

   For Math:
   Your 0.95 t confidence interval is (448.2561338314995,473.6869804542148)
   For Reading:
   Your 0.95 t confidence interval is (449.1937943789569,472.80078847818595)
   For Science:
   Your 0.95 t confidence interval is (453.8991748650865,476.9790108491992)

   It looks like we can say with 95% confidence that the mean score in math...
