I can not for the life of me figure out what I'm doing wrong with Tukey HSD. I provided the Q table I have been given at the bottom as well.
Here I need help with 4-b
8 Exercise 13-41 Static 3.33 First National Bank employs three real estate appraisers whose job is to establish a property's market value before the bank offers a points mortgage to a prospective buyer. It is imperative that each appraiser values a property with no bias. Suppose First National Bank wishes to check the consistency of the recent values that its appraisers have established. The bank asked the three appraisers to value (in $1,000s) three different types of homes: a cape, a colonial, and a ranch. The accompanying table shows the results. Assume that values are normally distributed. (You may find it useful to reference the q table.

Round "SS" and "MS" to 2 decimal places, and "F' and "p-value" to 3 decimal places.) Answer is complete and correct.

At the 5% significance level, can you conclude that the average values differ by appraiser? O Yes, since the p-value associated with appraiser is less than significance level. O Yes, since the p-value associated with appraiser is greater than significance level. O No, since the p-value associated with appraiser is less than significance level. No, since the p-value associated with appraiser is greater than significance level. a-3. Should the bank be concerned with appraiser inconsistencies? O Yes O No O b. At the 5% significance level, can you conclude that the average values differ by house type? Yes, since the p-value associated with house type is less than significance level. O Yes, since the p-value associated with house type is greater than significance level. O No, since the p-value associated with house type is less than significance level. O No, since the p-value associated with house type is greater than significance level. c. If average values differ by house type, use Tukey's HSD method at the 5% significance level to determine which averages differ. (If the exact value for a, - c is not found in the table, use the average of corresponding upper & lower studentized range values. Negative values should be indicated by a minus sign.
