Q3. The following data are from a completely randomized design. [Multiple choice with single answer]

At the α = 0.05, test whether the means for the three treatments are equal.

(C). Is there a significant difference between the means for treatments A and B?

(a) Yes, because 32.75≠39.5

(b) No, because 32.75<>

(c) No, because 6.75>LSD

(d) Yes, because -6.75<>

(e) Yes, because 6.75<>

(f) None of the above

(D). Is there a significant difference between the means for treatments B and C?

(a) Yes, because 39.5≠37.5

(b) Yes, because 2<>

(c) No, because 2<>

(d) No, because -2<>

(e) Yes, because -2<>

(f) None of the above
