Show your work below.According to the Pew Research Center, the proportion of the American population who use only a cellular telephone (no landline) is 0.37. Jason conducts a survey of thirty 20- to 24-year-olds who live on their own and finds that 16 do not have a landline to their home. Does this provide sufficient evidence to conclude that the proportion of 20- to 24-year-olds who live on their own and don’t have a landline is greater than 0.37? Use an a=0.10 level of significance.

- Comcast Corporation is the largest cable television company, the second largest Internet service provider, and the fourth largest telephone service provider in the United States. Generally known for quality and reliable service, the company periodically experiences unexpectedservice interruptions. On January 14, 2014, such an interruption occurred for the Comcastcustomers living in southwest Florida. when customers called the Comcast office, a recordedmessage told them that the company was aware of the service outage and that it was anticipated that service would be restored in two hours. Assume that two hours is the mean time todo the repair and that the repair time has an exponential probability distribution.a. what is the probability that the cable service will be repaired in one hour or less?b. what is the probability that the repair will take between one hour and two hours?c.
