TABLE 11-4 An Agronomist Wants to Compare the Crop Yield of 3

question 202

Short Answer

TABLE 11-4
An agronomist wants to compare the crop yield of 3 varieties of chickpea seeds. She plants 15 fields, 5 with each variety. She then measures the crop yield in bushels per acre. Treating this as a completely randomized design, the results are presented in the table that follows.
Trial Smith Walsh Trevor
1 11.1 19.0 14.6
2 13.5 18.0 15.7
3 15.3 19.8 16.8
4 14.6 19.6 16.7
5 9.8 16.6 15.2
-Referring to Table 11-4, the null hypothesis will be rejected at a level of significance of 0.01 if the value of the test statistic is greater than ________.

Definitions:

Synchronous Motor

A type of AC motor that operates at a speed directly proportional to the frequency of the current supply.

Power Factor Correction

Adding capacitance or inductance to a circuit to cause the current and voltage to become more in phase with each other.

Synchronous Condenser

A term used to describe a synchronous motor that is used to provide power factor correction.

Synchronous Speed

The speed at which the magnetic field in an AC machine rotates, typically in motors or generators, determined by the machine's electrical frequency and the number of magnetic poles.
