Question 15
A Pew Poll in 2010, found that 50% of adults aged 2529 had access to only a cell phone, while 40% had access to both a cellphone and landline and 10% had access to only a landline. We wish to conduct a Goodness of Fit Test to see if the results of a poll of a random sample of 130 adults aged 2529 are significantly different from the 2010 poll results.
The random sample of 130 adults found that 69 had access to only a cell phone, 39 had access to only a landline, and 22 had access to both types of phones.

B. 
Ho: The distribution is the same as in 2010. Ha: The distribution is different than in 2010.
