Given the graph below,create a grouped

frequency distribution. Amount per adult
movie ticket. Los Angeles 12, New Orleans 9, Atlanta 7and a half, New York
12, Tokyo 20, Paris 17, Munich 15.
I don't know how to post the graph but
these are the shaded areas.

To create a grouped frequency distribution for the given data, you need to first determine the range of values and then divide them into appropriate intervals or groups.

Here's how you can create a grouped frequency distribution for the provided data:

Step 1: Determine the range of values
The range of values is the difference between the largest and smallest values. In this case, the smallest value is 7.5 and the largest value is 20. So, the range is 20 - 7.5 = 12.5.

Step 2: Decide on the number of intervals (groups)
To determine the number of intervals, you can use the square root of the total number of data points. In this case, there are 7 data points, so the square root is approximately 2.64. Since you cannot have a fraction of an interval, you can round it up to 3. Therefore, we will have 3 intervals.

Step 3: Calculate the width of each interval
To calculate the width of each interval, divide the range (12.5) by the number of intervals (3). Therefore, the width of each interval will be approximately 4.17.

Step 4: Determine the upper and lower limits for each interval
Start by selecting a lower limit that is less than or equal to the smallest value (7.5). Let's choose 7 as the lower limit for the first interval.

Interval 1:
Lower limit: 7
Upper limit: 7 + 4.17 = 11.17

Interval 2:
Lower limit: 11.17 + 0.01 (to avoid overlap)
Upper limit: 11.17 + 4.17 = 15.34

Interval 3:
Lower limit: 15.34 + 0.01 (to avoid overlap)
Upper limit: 15.34 + 4.17 = 19.51

Step 5: Count the frequency in each interval
Now, you need to count the number of data points that fall into each interval:

Interval 1: 7 ≤ x < 11.17 => 1 frequency
Interval 2: 11.17 ≤ x < 15.34 => 3 frequencies
Interval 3: 15.34 ≤ x < 19.51 => 3 frequencies

So, the grouped frequency distribution for the given data is as follows:

```
Interval Frequency
7 ≤ x < 11.17 1
11.17 ≤ x < 15.34 3
15.34 ≤ x < 19.51 3
```

Note: The data provided seems to be the amount per adult movie ticket in different cities. However, the shaded areas you mentioned are not clear without the graph. Nevertheless, the process of creating a grouped frequency distribution remains the same.
