Answer 1

To effectively analyze the survey results, we can organize the data by gender and calculate some statistics such as the total number of bars consumed, the average number of bars consumed per person in each gender group, and the overall average.

Let's summarize the data first:

Male Responses:

• 1 bar
• 13 bars
• 1 bar
• 30 bars
• 10 bars
• 3 bars
• 8 bars
• 5 bars
• 2 bars
• 19 bars
• 2 bars
• 9 bars
• 11 bars
• 25 bars
• 0 bars
• 2 bars
• 6 bars
• 28 bars
• 25 bars
• 0 bars
• 13 bars
• (Total: 21 males)

Female Responses:

• 14 bars
• 4 bars
• 0 bars
• 10 bars
• 1 bar
• 16 bars
• 16 bars
• 0 bars
• (Total: 9 females)

Totals and Averages

Now let's calculate the totals and averages.

1. Total candy bars consumed by males:

   • Total bars = 1 + 13 + 1 + 30 + 10 + 3 + 8 + 5 + 2 + 19 + 2 + 9 + 11 + 25 + 0 + 2 + 6 + 28 + 25 + 0 + 13 = 278 bars

2. Total candy bars consumed by females:

   • Total bars = 14 + 4 + 0 + 10 + 1 + 16 + 16 + 0 = 61 bars

3. Overall total:

   • Total bars consumed = 278 (males) + 61 (females) = 339 bars

4. Averages:

   • Average for males = Total bars by males / Number of male respondents = 278 / 21 ≈ 13.24 bars
   • Average for females = Total bars by females / Number of female respondents = 61 / 9 ≈ 6.78 bars
   • Overall average = Total bars consumed / Total respondents = 339 / 30 ≈ 11.30 bars

Summary:

• Total Bars Consumed by Males: 278
• Total Bars Consumed by Females: 61
• Overall Total Bars Consumed: 339
• Average Bars Consumed by Males: ≈ 13.24
• Average Bars Consumed by Females: ≈ 6.78
• Overall Average: ≈ 11.30

This analysis provides insight into candy consumption trends among the surveyed group of friends, which can be useful for planning their candy bar sales strategy.
