help fast Helena is in charge of selling tickets for the upcoming play at Willowbrook school. Each drama club member has been asked to sell tickets to friends and family members, and Helena wants to know approximately how many tickets have been sold so far.
First she asked five drama club members in her homeroom how many they had sold. Then she took ten samples from the entire drama club of 75 students.
Find the mean to the nearest tenth for each set of data.

Answer:
The mean number of tickets sold is 16.0 and 22.5
hope it helps :-)
Let's assume that the number of tickets sold by the five drama club members in Helena's homeroom are: 12, 15, 20, 10, 8.
To find the mean, we need to add up all the numbers and divide by the total number of values:
Mean = (12 + 15 + 20 + 10 + 8) / 5
Mean = 65 / 5
Mean = 13
Therefore, the mean number of tickets sold by the five drama club members in Helena's homeroom is approximately 13.
Next, let's assume that the number of tickets sold by the ten drama club members chosen randomly from the entire drama club are: 5, 8, 10, 12, 15, 18, 20, 22, 25, 28.
To find the mean, we need to add up all the numbers and divide by the total number of values:
Mean = (5 + 8 + 10 + 12 + 15 + 18 + 20 + 22 + 25 + 28) / 10
Mean = 173 / 10
Mean = 17.3
Therefore, the mean number of tickets sold by the ten randomly selected drama club members is approximately 17.3.
Note: We rounded the mean to the nearest tenth as per the question's requirement.
