The mean of a meteoritic score is 54.71. it is positively skewed data. Only 16 movies are of the category in a robot. Their average metacritique ranking is 54.66667 which shows that it is very close to the on an average metacritique ranking.
C. Ans
Boxandwhisker plot for the distribution of the gross revenue:
D. Ans
Correlation between a rating of a film and the revenue
0.160167647
They are positively correlated so we can say that both the data is in the same direction. If one is increasing then another will also increase.

No of action films analyses: = 13
Mean of their gross income = 228.38 millions
P value for the liklyhood test = 0.003102892 . so it is very less probable that film earn this much amount.

The regression line found In the previous examples tells the relationship between Y Gross Revenue in Millions of US$ and X Number of theatres. P value in this test is equal to 5.71E11. This less than 0.05 so we can say that we need to accept the null hypothesis. The intercept of the coefficient is 93.6278 and the standard error in this 75.2322.
The regression line in above case can be written as
Y = 159.867 + 0.047216 X_{1} + 1.354561 X_{2}+ 65.2928 X_{3} + 46.23357 X_{4} + 13.34658 X_{5} + 12.27422 X_{6} + 13.32961 X_{7} + 0 X_{8}
It is a relationship between Gross Revenue in Millions of US$ and other variables. The gross revenue can be predicted from the number of theaters and other variables. The intercept part is 159.867. it is negative so we can say that in the case where all variables are 0 then it shows the negative gross income so there is a loss in this business. The coefficient of last variable is 0 , it means that it does not affect the gross income.

The adjusted R squire is a modified version of R squire. In the prediction of the output we modified the relation and it shows that the updated r squire. If the adjusted R squire is larger than it means that the expected value is larger than the actual one.
K. Ans
Since p value is less than 0.05 in all cases except X_{3}, X_{4}, X_{5} so we can say that overall modal satisfying the required significance except these variables.
L. Ans
There are eight independent variables which effect the gross revenue in this regression modal but since the coefficient of X_{8} is 0 so we can say that except thriller all other factors effects the gross profit.
It is given that
Y gross profit
X1 Metacritique score of 30
X2 Shows in 4,000 theatres
X3 Not a sequel or a reboot

Following graph shows the connection among these three variables. The curves shows that the nonlinear distribution of Gross profit, the theatres. The graph of metacritique shows the linear distribution or we can say that it is closed to linear distribution.
The above analysis tells very much information about the movies interest Australia. We can see that only 16 movies are of category reboot. On other side 15 movies are of comedy category their average metacritique ranking is 51.66667. it is very less in the case of metacritique ranking of the movies which are under reboot category. So it directly tells that most of the people taking interest in the movies of reboot category. This interest is larger than the movies of action categories. There are 14 movies are of categories in action so we can see that the average of the metacritique ranking of these movies is 52.71429. it is less than the average ranking. The average gross income of action movies is 156.37. it is larger than the average income of all type of the movies so we can try to analyze this interest also.
