Question

What are companies’ biggest obstacles to attracting the best talent? Of 406 surveyed U.S. talent acquisition professionals, 215 reported that competition is the biggest obstacle at their company. At the 0.05 level of significance, is there evidence that the proportion of all talent acquisition professionals who report competition is the biggest obstacle to attracting the best talent at their company is different from 50%?

Answer 1

 

This is the two tailed test .

The null and alternative hypothesis is

H₀ : p = 0.50

H_a : p 0.50

= x / n = 215 / 406 = 0.5296

Test statistic = z

= - P₀ / [P_{0 *} (1 - P₀ ) / n]

= 0.5296 - 0.50 / [(0.50 * 0.50) / 406]

= 1.19

P-value = 0.2336

= 0.05

P-value >

Fail to reject the null hypothesis .

There is sufficient evidence to suggest that the biggest obstacle to attracting the best talent at their company is different from 50% .
