Based on the ratings system and the summarize() and mean() functions, the code chunk to add is <u>summarize(mean(Rating))</u> and the mean rating is 3.185933.
<h3>How do you find the mean rating?</h3>
To find the mean rating, the complete code should be trimmed_flavors_df %>% summarize(mean(Rating)).
This code would allow you to see the mean rating of your data by combining the summarize() and mean() functions such that you can display summary statistics.
Because of the "mean()" function, the statistic that will be displayed is the mean rating which in this case would be 3.185933.

The <em>correct answer</em> is:
His height is 4.45 standard deviations above the mean.
Explanation:
A z-score is defined as the number of standard deviations a data point is away from the mean.
Since his z-score is positive, this means his height is above the mean.
Since the z-score is 4.45, this is how many standard deviations away from the mean his height is.

Step-by-step explanation:
Dimensions of the rooms are as follows;
Room 1; 9 feet × 12 feet
Room 2; 14 ft × 16 ft
Room 3; 12 ft × 14 ft
Perimeter of rooms;
P1 = 2(9 + 12) = 42 ft
P2 = 2(14 + 16) = 60 ft
P3 = 2(12 + 14) = 52 ft
Total perimeter; P = 42 + 60 + 52 = 154 ft
Height is 90 ft.
Thus, total area is;
A = 154 × 90
A = 13860 ft²
Rate of painting is 160 per Sq.ft.
Thus amount to paint entire area = 160 × 13860 = 2217600
