Unless otherwise indicated, round your only nal answers (not the middle steps) to two decimal places. There is a hint given for problems you might want to use. Problem # 1. The National Health Interview Survey reports that 41% of the telephone users no longer use landlines, and have switched completely to cell phone use. Suppose we take random sample of 10 telephone users. Use the table below to answer the question a. P = 0.41 0.0051 0.0355 0.1111 0.2058 0.2503 0.2087 0.1209 0.0480 0.0125 LomummthI-on 0.0019 H O a) Find the probability that the sample contains at least 5 users who have abandoned their landlines? Show all your steps. Hint: P(X at least 5) = P( x= 5)+ P( X= 6)+ P( X= 7)+ P( x= 8)+ P( X= 9)+ P( x= 10) b) Assume that the National Health Interview Survey reports that 44% of telephone users no longer use landlines and have switched completely cell phone use. Suppose we take a random sample of 10 telephone users. Find the probability that the sample contains exactly 5 users who have abandoned their landlines? Show all your steps. I-Iint: use the binomial probability formula. Problem # 2. The following frequency distribution table represents the time (in seconds) it takes the victim of a crime to call the police. Find the class Width, class midpoints, class boundaries, the relative frequency and the cumulative frequency? Time Frequency 0 -59 1 60-1 19 2 120-179 5 180-239 14 240-299 7 300-3 59 12 360-419 9 Construct a 'equency histogram? Show all your steps
