Question

All persons running for public office must report the amount of money spent during their campaign. Political scientists have contended that female candidates generally find it difficult to raise money and therefore spend less in their campaign than male candidates. Suppose the accompanying data represent the campaign expenditures of a randomly selected group of male and female candidates for the state legislature. Do the data support the claim that female candidates generally spend less in their campaigns for public office than male candidates? Campaign Expenditures (in thousands of dollars)

candidate 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

female 169 206 257 294 252 283 240 207 230 183 298 269 256 277 300 126 318 184 252 305

male 289 334 278 268 336 438 388 388 394 394 425 386 356 342 305 365 355 312 209 458

is this independent or paired data and why? which t test would be appropriate to compare the two group? what is the p-value?
