Use the information below to answer questions17-18. A research is conducted to determine disease detection ability of a testing machine. We know that the probabilitythat machine will detect the disease is 50%. The probability that the machine is notfaulty is 60%, the machine ability to detect disease if it is not faulty is 80%.
17. Write down the value for the probability that the machine has the ability to detect disease or is not faulty......................................18. Write down the value for the probability that the machine has the ability to detect disease if it is faulty...................................
Use the information below to answer question . Data measured on n=3,539 participants who attended the seventh examination of the Offspring in the Framing- ham Heart Study showed that the mean Total Serum Cholesterol for men is 192.4 with sample size 1,544, whereas the mean Total Serum Cholesterol for women is 207.1 with sample size 1,766. The population standard deviation for men is 35.2 and 36.7 for women. We now wish to assess whether there is a statistically significant difference in mean Total Serum Cholesterol between men and women using a 5% level of significance.
2. Given that the table or the critical value is -1.96, do we accept or reject the claim that the mean weight is 191 and why?........................................................................... ...............................................................................................
