Question

jeanfrank works as a server in a small restaurant, where he can earn a tip (extra money) from each customer she serves. the histogram below shows the distribution of his 60 tip amounts for one - day of work. what must be true according to the histogram above? one of the tips were $8.00 his mean and median amount collected in tips are the same. the higher value of tips for jeanfrank arent automatically considered an anomaly, however, they are just less common in this workday there is a positive skew for jeanfranks tips there was a collection error that occurred for this to distribution to be rendered.

Explanation:

Step1: Analyze each option

• Option 1: The histogram has intervals (0 - 5, 5 - 10 etc.), we can't be sure if there is a tip of exactly $8.00$.
• Option 2: To check mean - median equality, we would need more information than just the histogram's shape.
• Option 3: The higher tip values (15 - 20) are less frequent but not outliers in an obvious sense without further statistical tests. They are just less common in this data set for the day's work.
• Option 4: The tail of the distribution extends to the right (higher tip values), so there is a positive skew.
• Option 5: There is no evidence in the histogram to suggest a collection error.

Answer:

The higher value of tips for Jeanfrank aren't automatically considered an anomaly, however, they are just less common in this workday; There is a positive skew for Jeanfrank's tips.
