6.38 Dining court survey. The dining court closest to your university residence has been redesigned. A survey is planned to assess whether or not students think that the new design is an improvement. It will contain eight questions; a seven-point scale will be used for the answers, with scores less than 4 favoring the previous design and scores greater than 4 favoring the new design (to varying degrees). The average of these eight questions will be used as the student’s response. State the null and alternative hypotheses you would use for examining whether or not the new design is viewed more favorably.
