<h3>How to create hypothesis?</h3>
We are given;
Population Proportion; p = 17.6% = 0.176
Sample size; n = 300
Sample proportion; p^ = 45/300 = 0.15 = 15%
Formula for standard deviation here is;
σ = √(pq/n)
σ = √(p(1 - p)/n)
σ = √(0.15 * 0.85/300)
σ = 0.0206
Formula for z-score is;
z = (p^ - p)/σ
z = (0.176 - 0.15)/0.0206
z = 1
From online p-value from z-score at significance level of 0.05, we have;
p = 0.1587
The p-value is greater than the significance value and so we fail to reject the null hypothesis and conclude that the proportion of underemployed residents in Thicksburg is lower than elsewhere in the country.
