Hi can you help me with 1 to number 6 please!!!!!!! A study was done to look at the relationship between number of movies people watch at the theater each year and the number of books that they read each year. The results of the survey are shown below. Movies 8 1 0 8 9 2 1 8 1 4 9 Books 6 14 16 11 5 10 14 8 11 13 8 r2 = ___________ (Round to two decimal places) Interpret r2 : There is a large variation in the number books people read each year, but if you only look at people who watch a fixed number of movies each year, this variation on average is reduced by 69%. There is a 69% chance that the regression line will be a good predictor for the number of books people read based on the number of movies they watch each year. 69% of all people watch about the same number of movies as they read books each year. Given any fixed number of movies watched per year, 69% of the population reads the predicted number of books per year. The equation of the linear regression line is: y^ = ______ + _______ x (Please show your answers to two decimal places) Use the model to predict the number of books read per year for someone who watches 4 movies per year. Books per year =_________ (Please round your answer to the nearest whole number.) Interpret the slope of the regression line in the context of the question: The slope has no practical meaning since people cannot read a negative number of books. For every additional movie that people watch each year, there tends to be an average decrease of 0.78 books read. As x goes up, y goes down. 6. Interpret the y-intercept in the context of the question: The y-intercept has no practical meaning for this study. The average number of books read per year is predicted to be 14 books. If someone watches 0 movies per year, then that person will read 14 books this year. The best prediction for a person who doesn't watch any movies is that they will read 14 books each year.
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.

Movies | 8 | 1 | 0 | 8 | 9 | 2 | 1 | 8 | 1 | 4 | 9 |
---|---|---|---|---|---|---|---|---|---|---|---|
Books | 6 | 14 | 16 | 11 | 5 | 10 | 14 | 8 | 11 | 13 | 8 |
- r2 = ___________ (Round to two decimal places)
- Interpret r2 :
- There is a large variation in the number books people read each year, but if you only look at people who watch a fixed number of movies each year, this variation on average is reduced by 69%.
- There is a 69% chance that the regression line will be a good predictor for the number of books people read based on the number of movies they watch each year.
- 69% of all people watch about the same number of movies as they read books each year.
- Given any fixed number of movies watched per year, 69% of the population reads the predicted number of books per year.
- The equation of the linear regression line is:
y^ = ______ + _______ x (Please show your answers to two decimal places) - Use the model to predict the number of books read per year for someone who watches 4 movies per year.
Books per year =_________ (Please round your answer to the nearest whole number.) - Interpret the slope of the regression line in the context of the question:
- The slope has no practical meaning since people cannot read a negative number of books.
- For every additional movie that people watch each year, there tends to be an average decrease of 0.78 books read.
- As x goes up, y goes down.
- The y-intercept has no practical meaning for this study.
- The average number of books read per year is predicted to be 14 books.
- If someone watches 0 movies per year, then that person will read 14 books this year.
- The best prediction for a person who doesn't watch any movies is that they will read 14 books each year.
