A certain disease has an incidence rate of 0.8%. If the false negative rate is 6% and the false positive rate is 4%, compute the probability that a person who tests positive actually has the disease. Give your answer accurate to at least 3 decimal places

The distances golf balls travel under laboratory testing conditions are normally distributed. The mean is 313 yards. The probability the golf ball travels further than 322 yards is 0.13. Find the probability a randomly selected golf ball travels between 304 yards and 322 yards. Express the answer as a decimal value rounded to the nearest hundredth.

The life of lightbulbs is distributed normally. The standard deviation of the lifetime is 20 hours and the mean lifetime of a bulb is 600 hours. Find the probability of a bulb lasting for at most 640 hours. Round your answer to four decimal places

Trucks in a delivery fleet travel a mean of 8080 miles per day with a standard deviation of 3030 miles per day. The mileage per day is distributed normally. Find the probability that a truck drives at least 5252 miles in a day. Round your answer to four decimal places.

Assume that adults have IQ scores that are normaly distributed with a mean of u= 100 and a standard deviation o = 15. Find the probability that a randomly selected adult has an IQ less than 121.

The average cost for two people to go to a movie is $18. The standard deviation is $4. Assume the cost is normally distributed. Using a graphing calculator find the probability that at any given theater, the cost will be more than $20 for two people to go to the movie. Please round to three decimal places. The probability that at any given theater, the cost will be more than $20 for two people to go to a movie is X S

The weights of steers in a herd are distributed normally. The standard deviation is 200lbs and the mean steer weight is 1400lbs. Find the probability that the weight of a randomly selected steer is between 1539 and 1679lbs. Round your answer to four decimal places.
