Increasing numbers of businesses are offering child-care benefits for their workers. However, one union claims that more than 85
Lubov Fominskaja [6]

Answer:

The p value for this test is given p_v = 0.1071

Since the p value is higher than the significance level given of \alpha=0.05 we have enough evidence to FAIL to reject the null hypothesis. And we can say that the true proportion of firms in the manufacturing sector still do not offer any child-care benefits to their workersis is not significantly higher than 0.85 or 85% at 5% of significance.

Step-by-step explanation:

We define the proportion of interest as p who represent the true proportion of firms in the manufacturing sector still do not offer any child-care benefits to their workers

And we want to anaylze the following system of hypothesis:

Null hypothesis: p \leq 0.85

Alternative hypothesis: p >0.85

And the statistic for this test is given by:

z =\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}}

The p value can be calculated with this formula:

p_v = P(z>z_{calc})

And the p value for this test is given p_v = 0.1071

Since the p value is higher than the significance level given of \alpha=0.05 we have enough evidence to FAIL to reject the null hypothesis. And we can say that the true proportion of firms in the manufacturing sector still do not offer any child-care benefits to their workersis is not significantly higher than 0.85 or 85% at 5% of significance.
