Final answer:
To calculate the population standard deviation of TV show ratings for specific seasons, the actual rating data are needed. The process involves finding the mean of the data set, calculating the squared deviations from this mean, summing these squared deviations, dividing by the number of data points, and finally taking the square root of this quotient.
Step-by-step explanation:
To calculate the population standard deviation of the ratings for the 2007-2008 and 2012-2013 seasons, we would need the actual rating percentages for each of the TV shows from those seasons. Unfortunately, the specific data required to perform these calculations were not provided in your question. However, I can guide you through the general process of calculating the population standard deviation:
- Collect all the rating percentages to form your data set.
- Find the mean (average) of those ratings.
- Subtract the mean from each rating to find the deviation of each data point from the mean.
- Square each of these deviations.
- Sum up all of the squared deviations.
- Divide this sum by the number of data points (since this is a population standard deviation).
- Take the square root of the result from step 5. This gives you the population standard deviation.
Without the specific ratings data, the question can't be answered definitively. If you come across the ratings data, you can use the above steps to calculate the population standard deviation for both seasons.
