Consider a multinomial experiment with n = 275 and k = 4. The null hypothesis to be tested is H0: p1 = p2 = p3 = p4 = 0.25.

Suppose that in a certain hypothesis test the null hypothesis is rejected at the .10 level; it is also rejected at the .05 level; however it cannot be rejected at the .01 level. The most accurate statement that can be made about the p-value for this test is that: p-value = 0.01. p-value = 0.10. 0.01 < p-value < 0.05. 0.05 < p-value < 0.10. Complete the sentence: If we do not reject the null hypothesis, we conclude that _____....

Suppose that a laboratory analyzes biological specimens to determine the concentration of toxins. The laboratory analyzes each specimen five times and reports the mean results. The five measurements for a given specimen are not all equal, but the results follow a normal distribution almost exactly. Assume the mean of the population of all repeated measurements, μ , is the true concentration in the specimen. The standard deviation of this distribution is known to be 0.2000 ppm. One of the laboratory’s...

You are conducting an experiment in which you measure two means. Your null hypothesis is that they are the same (i.e. μ1 - μ2 = 0) and your experiment will test this hypothesis with a confidence level of alpha = 0.05. You would like to be able to detect a difference in means of+/- 1 with a probability of at least 0.9. How many samples do you need to test? The standard deviations of the two groups are σ1 =...

An experiment consists of selecting a card from a standard deck of 52 cards, noting whether or not the card is an Face Card (Jack, Queen or King) and returning the card to the deck. This experiment is repeated 10 times. Let X be the random variable representing how many times out of the 10 you observe a Face Card. Suppose that you repeat the experiment 5070 times. Let Y be the random variable representing the number of Face Cards...
