Here is a histogram of Rating of all n= 456 of the movies in the sample. Possible ratings are numbers between 1 and 10. The histogram shows class boundaries with no gaps in between. %3D a) Based on the shape of this distribution, will the mean be MoviesDatae006Samplo456 bigger than the median, or will the mean be smaller than the 0.25 median, or will the mean be the same as the median? Since the 0.20 distribution seems to be left-skewed, mean will be smaller than the median 0.15 b) Are the numbers on the vertical axis proportions or are the numbers counts of movies? They are proportions. Counts are always 0.10 0.05 whole numbers c) Use the histogram to find the proportion of movies with 10 rating rating less than 7. (Approximate value is fine) we need to count the heights of first 4 bars. proportion of movies with rating less than 7- 0.01+0.025+0.0640.13 fiae aerey af rating

Here is a histogram of Rating of all n= 456 of the movies in the sample. Possible ratings are numbers between 1 and 10. The histogram shows class boundaries with no gaps in between. a) Based on the shape of this distribution, will the mean be MoviesDatase006Sample4s6 bigger than the median, or will the mean be smaller than the 0.25 median, or will the mean be the same as the median? Since the E0.20 distribution seems to be left-skewed, mean will be smaller than the median 0.15 b) Are the numbers on the vertical axis proportions or are the *0.10 numbers counts of movies? They are proportions. Counts are always 0.05 whole numbers c) Use the histogram to find the proportion aolf movies with rating rating less than 7. (Approximate value is fine) we need to count the heights of first 4 bars. proportion of movies with rating less than 7 = 0.01+0.025+0.0640.13 Desktop 54°F Sunny DELL F6 F7 F8 F9 F10 F11 F12 PrtScr Insert & 7 1O Y
