Question

An Employee Value Proposition​ (EVP) is about defining the essence of a company. The EVP is the value an employee receives from the​ employer; it defines the commitment the company will make to develop the employee in exchange for the effort the employee puts in to benefit the company. But do all agree on what makes a unique and compelling​ EVP? A study showed that 13​% of business​ executives, 35​% of HR​ leaders, and 33​% of employees say that compensation​ (pay and​ rewards) makes for a unique and compelling EVP. Assume that 200 individuals within each business group were surveyed. Complete parts​ (a) through​ (c).

a. Is there evidence of a significant difference among business groups with respect to the proportion that say compensation​ (pay and​ rewards) makes for a unique and compelling​ EVP? Use a=0.05

The test statistic is x^2stat=

The critical value for

b. Determine the​ p-value in​ (a) and interpret its meaning.

Answer 1

		c1	c2	c3	sum
	r1	26	70	66	162
	r2	174	130	134	438
	sum	200	200	200	600
	Eij	1	2	3
expected	1	54	54	54
	2	146	146	146
	Oi	26	70	66	174	130	134
	Ei	54	54	54	146	146	146
								sum
	(Oi-Ei)^2/Ei	14.51852	4.740741	2.666667	5.369863	1.7534	0.9863	30.036
							alpha	0.05
							critical value	5.991
							p-value	0.0000

TS = 30.036

critical value = 5.991

reject Ho , there is sufficient evidence

b)

p-value = 0.000

p-value is probability of obtaining a result as extreme as one obtained with this sample given that null is true
