Astronaunts often report that there are times when they become disoriented as they move around in zero-gravity. Therefore, they ususally rely on bright colors and other visual information to help them estabish a top-down orientation. A study was conducted to asses the potential of using color as body orienting.60college students, reclining on their backs in the dark, found it difficult to establish orientation when positioned on under a rotating disk. This rotating disk was painted half black and half white. Out of the60students,56believed they were right side up when the white was on top.

Use this information to estimate the true proportion of subjects who use the white color as a cue for right-side-up orientation. That is, construct a90% confidence interval for the true proportion.
