5. The county park director is interested in the relationship between park size and attendance at the county's 25 parks. She has her staff collect data on the size of each park (in acres) and the average daily attendance for one month. When they regress average daily attendance on park size, they find that: ; s.e._b = 1.0; R² = .35.

(a) Interpret the slope.

(b) Interpret the p-value of the slope.

(c) Interpret the R-squared.

(d) The director would like to build a new park on the north side of the county that would attract an average daily attendance of 500 people. How large should the park be?

(e) The director has determined that the ratio of parking spaces to average daily attendance at county parks should be 1:10 - there should be one parking space for every 10 people who come to the park on an average day. If she builds a new park on the south side of the county that is 150 acres large, how many parking spaces should it have?
