Questions and tables on the image. A study on testicular cancer over the lifetime of a random sample of men over 70 years of age determined which testicle/s (L-left, R right) were cancer given in the table below. ous. The resulting data are Right testicle no 982 yes eft testicle no 10 a. Use the data in the above table to estimate the values below i. Pr(any cancer) PricancerLeft)- iii. Pr(cancer Right)- iv. Pr(cancer in Left)- v. Pr(cancer in Right)- vi. Pr(Left cancer Right cancer)- vi. If cancer occurs in left and right testicles independently how man men in the above table are expected to have both testicles cancerous? Use the data in the above table to determine the values below i. ii. ii. b. Number of men with 0 testicles cancerous Number of men with I testicle cancerous Number of men with 2 testicles cancerous Let y number of testicles with cancer and consider the grouped data below. frequency 982 10 a. Draw an absolute frequency histogram of y b. Draw the expected absolute frequency histogram if the occurrence of cancer in the two testicies are independent and identically distributed (iid). c. Give the value of the mean of y d. Give the value of the standard deviation of y e. Give the value expected for the standard deviation if the occurrence of cancer is iid in the two testicles. f. Give the valuc of the dispcrsion paramcter g. What do your answers to a-f infer about the occurrence of testicular cancer?
Explanation / Answer
a) Solving first 4 parts only
1) P( any cancer) = (4+4+10)/1000=18/1000
2)P( Cancer/Left) = 14/1000
3) P( cancer/right) = (10+4)/1000=14/1000
4)P( cancer in left only)= 4/1000
