John’s kidneys have failed and he is on the wait-list for a kidney transplant. If he gets a transplant, there is a chance that he will not survive the operation; if he survives the operation, there is a chance that the transplant is not successful, i.e. his body does not accept the new kidney. His doctor gives him the following information for his condition: 90% of patients survive the operation. Of the patients who survive, 60% of transplants are successful while 40% are not. What is the probability that John survives the operation and the transplant is successful?

Filtration is the process of eliminating undesirable ____ by the insertion of absorbing materials into the primary beam.

In 2003, American Psychological Association conducted a survey of a random sample of psychologists to estimate mean incomes for psychologists with various academic degrees and levels of experience. Of the 31 psychologists who received a masters degree in 2003, the mean income was $43,834 with a standard deviation of $16,870. Assuming that psychologists’ income follow a normal distribution, which of the following is the 95% confidence interval for the population mean?  

Total x-ray beam quality is numerically represented by the

As the kilovoltage increases, the percentage of photons that undergo a ____ interaction will decrease.

The number of attendees for weeknight shows follows a normal distribution with mean 1550 and a standard deviation of 180. One takes a sample of 36 weeknight shows and finds the sample mean

BONUS Suppose you are interested in knowing the proportion of Texas A&M students who have their own subscription to Netflix. You find a study that sampled 200 students that reports a Confidence Interval of (0.6679, 0.8121), but they did not report their Confidence Level. Assume that they correctly designed their study so that all assumptions for a Confidence Interval are met. Find the Confidence Level they used in constructing their interval. (Hint: the point estimate for the proportion (
