It is estimated that 75% of all young adults between the ages of 18-35 do not have a landline in their homes and only use a cell phone at home. For all sub-questions, if any final result is less than 0.001, you can round it to zero.(a) On average, how many young adults do not own a landline in a random sample of 100? (b) What is the standard deviation of probability of young adults who do not own a landline in a simple random sample of 100? (c) What is the proportion of young adults who do not own a landline? (d) What is the probability that no one in a simple random sample of 100 young adults owns a landline? (e) What is the probability that everyone in a simple random sample of 100 young adults owns a landline? (f) What is the distribution of the number of young adults in a sample of 100 who do not own a landline? (g) What is the probability that exactly half the young adults in a simple random sample of 100 do not own a landline? (h) What is the probability that more than 20% of the young adults in a simple random sample of 100 do not own a landline
