Maybe most of them thought it was a trick question, and were saying that they think they'll be more than just "this" physical body.
After all, Paul says in 1 Co 15: "44 it is sown a natural body, it is raised a spiritual body. "
There are going to be some very surprised people later on...
Who was the first person in heaven after Christ?
The Good Thief: "Today thou shalt be with me in paradise."
Look at my hands and my feet, that it is I myself. Touch me and see, because a ghost does not have flesh and bones as you can see I have."
And as he said this, he showed them his hands and his feet.
While they were still incredulous for joy and were amazed, he asked them, "Have you anything here to eat?"
They gave him a piece of baked fish;
he took it and ate it in front of them.

As you point out, it's hard to know what to think without the survey details.
Of course, there are all those Barna surveys about the lack of a Biblical world view even among those describing themselves as born again. In that light, maybe 36% is actually a big number.
We don't know what body we will have because we don't know what body Jesus will have...
But it won't be the body we have now..
1Co 15:47 The first man is of the earth, earthy: the second man is the Lord from heaven.
1Co 15:48 As is the earthy, such are they also that are earthy: and as is the heavenly, such are they also that are heavenly.
1Co 15:49 And as we have borne the image of the earthy, we shall also bear the image of the heavenly.
1Co 15:50 Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption.
Our flesh (and blood) is corrupt...Hence; the spiritual circumcism...
The Bible and the Resurrection
The Bible clearly affirms the doctrine of the general resurrection of the dead. Note, in brief, the following points.
The concept of the resurrection is found in the Old Testament - though not as pronounced as it comes to light in the New Testament (cf. 2 Tim. 1:10). According to Jesus, God’s declaration to Moses regarding Abraham, Isaac, and Jacob was an indication of the eventual resurrection (Mt. 22:31,32). Other Old Testament passages also suggested that man’s body would be raised ultimately (see Job 19:25-27; Psa. 17:15; Isa. 26:19; Dan. 12:2; Hos. 13:14).
The doctrine of the bodily resurrection is affirmed abundantly in the New Testament (see Jn. 5:28-29; 6:39-40; Mk. 12:18-27; Acts 17:32; 26:8; Rom. 8:23; 1 Thes. 4:16; 1 Cor. 15; 2 Cor. 5:1-2; Phil. 3:21).
How any person can read Paul’s great discussion of the eventual disposition of the dead - in 1 Corinthians, chapter 15 - and not believe in the resurrection, has to be one of the mysteries of the ages. In that remarkable chapter the apostle develops his line of argumentation in the following fashion.
Paul persuasively pled for the historical fact of the bodily resurrection of Jesus Christ on the basis of numerous eyewitnesses of the risen Lord. On one occasion, this consisted of more than 500 people (15:1-11).
The apostle maintained that the Lord’s resurrection is Heaven’s guarantee that we too shall be raised. Jesus is the “first-fruits” (a figure suggesting a future harvest) of the general resurrection to be effected at the time of His return (vv. 12-34).
Paul discussed the nature of the resurrected body. It will not be a physical or a corruptible body; rather, it will be spiritual and incorruptible (vv. 35-49). Nevertheless, there will be an identity continuum between our present body and the new, resurrected one. Only in this light can the term “resurrection” (which means to “stand up”) have any relevance. Moreover, each body will have its own individuality (v. 38). It is so thrilling to reflect upon the fact that our new body will be identical in form to the glorious body of our resurrected Lord (see Phil. 3:21).
Finally, the theological impact of the resurrection is set forth. It is a declaration of victory (vv. 50-57). In view of this great hope, saints are admonished to persevere in their fidelity (v. 58).
The biblical doctrine of the resurrection of the dead is a comforting concept. Those who would rob us of this hope are not friends of the cause of Christ.

With that said, to me, it seems as though the very forces (cranial electrical energy) that drive our reality here on earth, conscious or asleep, can easily continue for eternity by the Grace of The Almighty whether in Heaven or Hell simply by His will.
Individual perception is individual reality, here, in the now and forever.
I remember Jodie Foster referring to God in the movie 'Contact' and the enormity of the universe and 'what a waste of space, it would be if we were the only ones'. I have the same conclusions analogous as to each individual human spirit that was created by The Almighty would be a great waste. The power of the scientifically unexplainable emotion in that we may love one another, to be loved, and most importantly, give praise and thanks in that we may glorify His name by learning his word and keeping His commandments:
John 3
16. For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
Paul's right. The physical body only supports and enables the spirit. Jesus and Lazarus needed the physical to walk in this world. The Father used a "burning bush" to appear to Moses. The physical body gets recycled as dust and will pass away.
