According to the inc .com, 79 % of job seekers use social media in their job search in 2018.
00:10
Many believe that this number is inflated by the proportion of 22 -30 year olds who use social media in their job search.
00:26
A survey of 22 -30 year old job seekers showed that 310 of 370 used social media in their job search.
00:37
In addition, 275 of 370 responded indicated that they have electronically submitted their resume to an employee.
00:50
So what to conduct a hypothesis test to determine if the results of the survey justify concluding the proportion of the 22 -30 year olds who use social media in their job search exceed the proportion of the population that use social media in their job search.
01:10
So what to find the p -value and find our conclusion and to conduct the hypothesis test to determine if the results of the survey justify concluding that more than 70 % of them, of the job seekers, have electronically submitted their resume.
01:31
So for the first question, we have the population p as 0 .79.
01:37
The sample size is 310 and the sample proportion p is 310 over 370 which is 0 .8373, 7 8 rather.
01:55
So the null hypothesis would be p is equal to 0 .79 against p is greater than 0 .79...
