The manager of a seafood restaurant was asked to establish a pricing policy on lobster dinners. Experimenting with prices produced the following data:

Average Number

Sold per Day, y Price, x

240 $5.00 

233 5.25

225 5.50

216 5.75

211 6.00

204 6.25 

196 6.50 

190 6.75

190 7.00

191 7.25

184 7.50

179 7.75

Determine the correlation coefficient and interpret it. (Include the negative sign, as appropriate, directly before the value. Enter your "r" answer to 4 decimal places. Enter your first "r2" answer as a proportion (between 0 and 1) and to 2 decimal places. Then enter the next answer as the percentage equivalent to the nearest whole number percent. Omit the "%" sign in your response.)
