QUESTION 5 A manufacturer of a lightbulb claimed that its lightbulbs have a mean lifetime of 700 hours with a standard deviation of 120 hours. You purchased 144 of these lightbulbs with the idea that you would purchase more if the mean lifetime of your sample were more than 680 hours. What is the probability that you will not buy again from this manufacturer?

Suppose we are interested in the mean burning rate of a solid propellant, a random variable that can be described by a probability distribution. We are interested in deciding whether or not the mean burning rate is 50 centimeters per second. What could be a null hypothesis? And what could be the alternative hypothesis?
If X is a random variable with a mean of 20 and a standard deviation of 5, what is the probability that X is less than 15?
Suppose that unknown to a geneticist, there are 6 out of 12 genes that play a significant role in developing skin cancer. If the geneticist randomly samples 5 of these 12 genes and studies them, the probability that he will have sampled more than 4 skin cancer related genes is Note: Provide your answer in three decimal points e.g. 0.001
It is flu season again. On average 549 UCI students get sick, with a standard deviation of 30 students. If there are 600 or more students who get sick, there is an epidemic. What is the probability there will be an epidemic?
The producer of a weight-loss pill advertises that people who use the pill lose, after one week, an average (mean) of 1.75 pounds with a standard deviation of 1.02 pounds. In a recent study, a group of 60 people who used this pill were interviewed. The study revealed that these people lost a mean of 1.9 pounds after one week. If the producer's claim is correct, what is the probability that the mean weight loss after one week on this pill for a random sample of 60 individuals will be 1.9 pounds or less? Carry your intermediate computations to at least four decimal places. Round your answer to at least three decimal places.
You are interested in studying the average gestational length of pregnancies among African American women in the United States to see if it is different from the rest of the US population. The population mean for gestational length is 39 weeks with a standard deviation of 2 weeks. You take a simple random sample of 22 African American women that gave birth in the last year and find that their mean gestational length is is 38.5 weeks. If you decide to conduct a two-sided test with α = .05. What is the power of this test?
One year, the distribution of salaries for professional sports players had a mean of $1.6 million and a standard deviation of $0.7 million. Suppose a sample of 100 major league players was taken. Find the approximate probability that the average salary of the 100 players that year exceeds $1.1 million.
