In a previous​ year, 58​% of females aged 15 and older lived alone. A sociologist tests whether this percentage is different tod
Gemiola [76]

Answer:

z=\frac{0.565 -0.58}{\sqrt{\frac{0.58(1-0.58)}{600}}}=-0.744  

Since is a bilateral test the p value would be given by:  

p_v =2*P(z  

And since the p value is higher than the significance level we have enough evidence to conclude that the true proportion is not significantly different from 0.58

Step-by-step explanation:

Information given

n=600 represent the random sample selcted

X=339 represent the number of females aged 15 and older that living alone

\hat p=\frac{339}{600}=0.565 estimated proportion of females aged 15 and older that living alone

p_o=0.58 is the value that we want to check

\alpha=0.01 represent the significance level

z would represent the statistic

p_ represent the p value

Sytem of hypothesis

We want to check if the true proportion females aged 15 and older that living alone is significantly different from 0.58.:  

Null hypothesis:p=0.58  

Alternative hypothesis:p \neq 0.58  

The statistic is given by:

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

Replacing the info given we got:

z=\frac{0.565 -0.58}{\sqrt{\frac{0.58(1-0.58)}{600}}}=-0.744  

Since is a bilateral test the p value would be given by:  

p_v =2*P(z  

And since the p value is higher than the significance level we have enough evidence to conclude that the true proportion is not significantly different from 0.58
