The annual rainfall for two cities, Albany and Zachary, in each of the years from 2002 to 2011 are shown in the tables. Annual R

Masteriza [31]

Answer:

On average, Albani gets 20.933 inches of rain per year.

On average, Zachary gets 24.734 inches of rain per year.

On average, Zachary gets more rain than Albani.

Step-by-step explanation:

Mean is given by:

$Mean = \frac{Sum}{Total}$

For Albani :

Sum of total number of terms = 23.36+18.51+28.54+22.36+30.50+24.74+11.93+15.34+18.07+15.98

Sum of total number of terms = 209.33

Number of terms = 10

$Mean=\frac{209.33}{10}\\\\Mean=20.933\\$

For Zachary :

Sum of total number of terms = 27.27+20.11+31.14+25.88+32.97+25.03+18.55+23.91+22.75+19.73

Sum of total number of terms = 247.34

Number of terms = 10

$Mean=\frac{247.34}{10}\\Mean=24.734$

To determine wether voters would be willing to vote for tax increase to improve the citys parks, th3 park commission surveys 500

Romashka [77]

Answer:

B. Park users are more likely to be willing pay more to improve park.

Step-by-step explanation:

The sample is biased because it is only made up of people that patronize and use the park. They will be more willing to pay to improve the park because it satisfies and fulfills their needs.

This given sample is not representative of the poll as it is restricted to park users alone which are not the only tax payers in the area.

To have a more balanced representation, the whole population should be sampled irrespective of whether they are park users or not. This will give a fair representation.
