Unformatted text preview: MINITAB Assignment 3 1. For parts ac, copy and paste the MINITAB commands you used and the results found in the Session window . Use the cumulative probabilities found in part c to answer parts dg. Round answers to 4 decimal places. ————— 3/25/2010 8:56:17 AM ———————————————————— Welcome to Minitab, press F1 for help. MTB > let k1= 10*0.8 MTB > let k2= sqrt(10*0.8*(10.8)) MTB > print k1k2 Data Display K1 8.00000 K2 1.26491 a. The mean of the number of smokers who started when they were less than 18 years old from the sample of 10 smokers is 8.0. b. The standard deviation of the number of smokers who started when they were less than 18 years old from the sample of 10 adult smokers is 1.2649. c. MTB > cdf; SUBC> binom 10 0.8. Cumulative Distribution Function Binomial with n = 10 and p = 0.8 x P( X <= x ) 0 0.00000 1 0.00000 2 0.00008 3 0.00086 4 0.00637 5 0.03279 6 0.12087 7 0.32220 8 0.62419 9 0.89263 10 1.00000 The cumulative distribution function of the binomial with n = 10 and p = 0.8 is listed above. d. The probability that exactly 8 of the 10 smokers started before they were 18 is, (0.62419 0.322200.120870.032790.006370.000860.00008)= 0.1410.0....
