- Is carbon dating? Why does it work? Give an example in which carbon dating would be useful.arrow_forwardEstimate the age of a newly discovered fossil for which the ratio of carbon-14 to carbon-12 is R=1/1014.arrow_forward“Average adult Americans are about one inch taller, but nearly a whopping 25 pounds heavier than they were in 1960, according to a new report from the Centers for Disease Control and Prevention (CDC). The bad news, says the CDC, is that average BMI (body mass index, a weight-for-height formula used to measure obesity) has increased among adults from approximately 25 in 1960 to 28 in 2002.” Boston is considered one of America’s healthiest cities. Is the weight gain since 1960 similar in Boston? A sample of n = 25 adults suggested a mean increase of 17 pounds with a standard deviation of 8.6 pounds. Is Boston statistically significantly different in terms of weight gain since 1960? Run the appropriate test at a 5% level of significance.arrow_forward

The surgeon explains the risks to John: infection occurs in 4% of operations, the repair fails in 12% of operations, and both infection and failure occur together in 0.78% of operations. What percentage, P, of these operations succeed and are free from infection? Please round your answer to the nearest two decimal places. 1.62 P =arrow_forwardTire pressure monitoring systems (TPMS) warns the driver when the tire pressure of the vehicle is 28% below the target pressure. Suppose the target tire pressure of a certain car is 30 psi (a) at what psi will the TPMS trigger a warning for this car?arrow_forward
- Please don't provide hand writttin solution....arrow_forwardOne doctor claims that a person's diastolic blood pressure can be lowered if, instead of taking medicine, the person listens to a relaxation tape every night. Ten subjects are selected at random. Your blood pressure, measured in millimeters of mercury, is listed below. All 10 patients are given the tapes and asked to listen to them every night for a month. At the end of the month, their blood pressure is taken again. The data is listed below. Use alpha equals 0.05 to test the doctor's claim.arrow_forwardRadon-222 has a half-life of 4.00 days. Given its mass 2.789 gram at a certain time, what was the sample's mass (in gram) before 0.959 month? 1 month is about 30.5 days. MacBookDroarrow_forward
