A sample of 22 residents has an average age of 60.5 with a standard deviation of 4.28 years. What is the computed and cumulative probability if the population mean is 58.2? * Captionless Image a b c 3. A machine is designed to fill a bottle with 12 oz of soda, A sample of 15 bottles is randomly selected and noticed that the means is 11.8 oz and the standard deviation is 0.36 oz. Determine the percentile of the sample mean. * Captionless Image a b c 4. A sample of 10 motorcycles has an average mileage of 5725 with a standard deviation of 622.5 miles. Calculate the cumulative probability if the population mean is 6000. * Captionless Image a b c 5. A recent survey reports that the average company meeting in a month is 17. A researcher surveyed the 25 stakeholder of the same company and found to be 14.Calculate the area under curve if the standard deviation was 4. * Captionless Image a b c 6. A special cable has a breaking strength of 700 lbs. A researcher selects a sample of 15 cables and finds that the breaking strength is 692.31 lbs with a standard deviation of 10 lbs. Calculate the percentile of the sample mean. * Captionless Image a b c 7. A new ICT staff read a report that the average number of students using a computer laboratory per hour is 17. He then randomly selected a day to track the number of students who used the laboratory for 6 hours period. The results were as follows: 18 16 20 19 20 23 21 24. Determine the percentile of the sample mean. * Captionless Image a b c c
