Question

Determine the expected count under the null hypothesis.

Is achieving a basic skill level in a subject independent to the location of the school? A random sample of students categorized by the location of school and the number achieving basic skills in three subjects is shown in the table.

	Subject
Location of School	Reading	Math	Science	Totals
Urban	43	42	38	123
Suburban	63	66	65	194
Totals	106	108	103	317

Under the null hypothesis for a Chi-square test of independence, what would be the expected number of students achieving basic math skills in the urban schools?

Question 29 options:

	54.0
	52.8
	41.9
	41.0

Answer 1

Solution :

From given table,

The expected number of students achieving basic math skills in the urban schools is :

= (108 * 123) / 317

= 41.9
