They all were. There was some concern by a number of parties initially that the vocals on a few tracks were not Jackson's. I believe this was mainly caused by the original vocal track being speeded up/slowed down to match the tempo of the tracks. By this logic, the track 2000 Watts from the Invincible album contains an impersonator singing too!

Six of Michael’s former producers and engineers who had worked with Michael over the past 30 years – Bruce Swedien, Matt Forger, Stewart Brawley, Michael Prince, Dr. Freeze and Teddy Riley – were all invited to a listening session to hear the raw vocals of the Cascio tracks in question. All of these persons listened to the a cappella versions of the vocals on the Cascio tracks being considered for inclusion on the album, so they could give an opinion as to whether or not the lead vocals were sung by Michael. They all confirmed that the vocal was definitely Michael.
Michael’s musical director and piano player on many of his records over a 20-year period, Greg Phillinganes, played on a Cascio track being produced for the album, and said the voice was definitely Michael’s. Dorian Holley, who was Michael’s vocal director for his solo tours for 20 plus years (including the O2 Concert Tour) and is seen in the This Is It film, listened to the Cascio tracks and told me the lead vocal was Michael Jackson.
These are all engineers, producers and musicians who worked on tours and/or in the studio with Michael when he was recording Bad, Thriller, Off The Wall, Dangerous, Invincible, HIStory and Blood On The Dance Floor, and they all reconfirmed their belief that the lead vocals were Michael’s voice on the Cascio tracks.
The Estate then retained one of the best-known forensic musicologists in the nation to listen to the vocals without any instrumental accompaniment (“a cappella”), and to compare them with a cappella vocals from previous Michael songs. This expert performed waveform analysis, an objective scientific test used to determine audio authenticity, on the Cascio tracks, as well as previously released tracks with Michael’s voice, and reported that ALL of the lead vocals analyzed (which included Cascio tracks) were the voice of Michael Jackson.
Sony Music conducted their own investigation by hiring yet a second well-respected forensic musicologist who also compared the a cappella lead vocals from Cascio tracks against previously released vocals of Michael’s, and found that Michael’s voice was the on all sets of the raw vocals. The Cascio tracks were also played for two very prominent persons in the music industry who played crucial roles in Michael’s career. Both of these individuals believed that the lead vocals were Michael’s.
