Ok its two questions

Answer for number 1 is 2 cups
Answer for number 2 is 1555

Answer 2

Answer:

1-) 2 cups

2-) 1555 people

Step-by-step explanation:

1-) A quick glance at all three groups shows that group 3 is a clear outlier and thus it is likely biased. Considering just groups 1 and 2, the estimate mean number of of cups of coffee the customers drink in one day is:

$Mean = \frac{1+3+2+2+4+4+1+3+2+1}{10} \\Mean = 2.3$

Rounding it to the nearest whole number, the average is 2 cups.

2-) The percentage of people who prefer polar bears is roughly the ratio of interviewed people who prefer polar bear to the total number of people interviewed:

$P=\frac{46+43+49}{300} \\P=0.46$

In a weekend with 3380 visitors, a reasonable estimate of people who prefer polar bears is:

$N= 0.46*3380\\N= 1554,8$

Rounding to the nearest whole number, the estimate is 1555 people.
