A standardized IQ test is known to be normally distributed and has μ=100 and σ=10. there is a common belief that students in wealthier school districts tend to have higher IQ scores. A researcher randomly selects a sample of 25 students from wealthy school districts. The average IQ of the sample is x̅=103. Conduct a test if the average score for students from wealthy districts is higher than 100, assuming α=0.05
A nutritionist claims that the mean tuna consumption by a person is 3.4 pounds per year. A sample of 90 people shows that the mean tuna consumption by a person is 3.3 pounds per year. Assume the population standard deviation is 1.02 pounds. At α=0.03, can you reject the claim? (a) Identify the null hypothesis and alternative hypothesis. A.

Travis does research with a marine biology research team. His job is to catch lobsters, weigh them, tag them, and return them to the water. Over the years, the team has determined that the average weight in pounds of the lobsters caught at a particular location was µ = 2.1 lbs. with a σ of 1.8 lbs. As part of an annual survey, Travis catches 27 lobsters with a mean of 3.1 lbs. Is he correct in assuming that the lobsters he caught are significantly heavier that those usually found in that location? Please use α = .05 and a two-tailed test.
