Answer:
At 5% significance level, larger proportion of military personnel students protect their profiles on social-networking sites than young adults with profiles on social-networking sites.
Step-by-step explanation:
let p be the proportion of military personnel students who restrict access to their profiles. Then null and alternative hypotheses are:
: p=0.67 (67%)
: p>0.67
We need to calculate z-statistic of sample proportion:
z= where
- p(s) is the sample proportion of military students who restrict access to their profiles (
=0.78)
- p is the proportion assumed under null hypothesis. (0.67)
- N is the sample size (100)
Then z= ≈ 2.34
The corresponding p-value is 0.0096. Since 0.0096<0.05 (significance level) we can reject the null hypothesis and conclude at 5% significance level that larger proportion of military personnel students protect their profiles on social-networking sites than young adults with profiles on social-networking sites.
Answer:
Step-by-step explanation:
In order to find the value of x that makes m || n, we need to note something.
<u>When two parallel lines are cut by a transversal, their angle measures will be the same</u>.
Therefore, in order for m and n to be parallel, their two angles listed must be equivalent.
So, we can set these expression equal to each other and solve for x.
Therefore, x=23.
Hope this helped!
