A psychologist is studying smokers' self-images, which she measures by the self-image (SI) score from a personality inventory.

The psychologist gathers a random sample of 10 SI scores of smokers and finds that their mean is 177 and their standard deviation is 30. Assume that the population of SI scores of smokers is normally distributed with mean µ. Based on the sample, can the psychologist conclude that µ is different from 150?

CetaceaNow is a conservationist organization that monitors the health of whale and dolphin populations worldwide. As part of their work, they are modelling the lengths of killer whale calves that will be born over the next decade. For their model, CetaceaNow is using a normal distribution with a mean of 280 cm and a standard deviation of 20 cm. Use this table or the ALEKS calculator to find the percentage of killer whale calves with a length of between 269 cm and 299 cm according to the model. For your intermediate computations, use four or more decimal places. Give your final answer to two decimal places (for example 98.23%).

In a test of the effectiveness of garlic for lowering cholesterol, 81 subjects were treated with raw garlic. Cholesterol levels were measured before and after the treatment. The changes (before minus after) in their levels of LDL cholesterol (in mg/dL) have a mean of 0.9 and a standard deviation of 21.5. Use a 0.10 significanc level to test the claim that with garlic treatment, the mean change in LDL cholesterol is greater than 0. What do the results suggest about the effectiveness of the gar treatment? Assume that a simple random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim.
For the population of college students, the number of hours spent studying per week is normally distributed with a = 4.40 and = 2.32 hours. We surveyed a random sample of students majoring in psychology about the number of hours they spent studying this past week.

A study investigated about 3000 meals ordered from Chipotle restaurants using the online site GrubHub. Researchers calculated the sodium content, in milligrams (mg)m for each order based on Chipotle's published nutrition information. Let X= the sodium content for a randomly selected meal The distribution of X is approximately normal with mean 2000 mg and standard deviation 500 mg. What percent of the meals ordered exceeded the recommended daily allowance of 2400 mg of sodium?
