What is the test for making a sufficient prima facie showing to exclude a juror on the basis of race?

The trial court here found that the defense had not made a sufficient prima facie showing because the facts did not permit an inference of ethnic discrimination. On review from such a finding, we conduct "an independent review of the entire record to decide 'the legal question whether the record supports an inference that the prosecutor excused a juror on the basis of race' " or ethnicity. (People v. Taylor, supra, 48 Cal.4th at p. 614.)
