Researchers measured the amount of plasma carotenoids (in micrograms per milliliter) of male and female zebra finches. Here are some summary statistics from the study (note: standard error=standard deviation/sqrt(n)):

Sex	n	Mean	Standard Error
Males	50	31.77	1.85
Females	52	29.74	2.02

Do male and female zebra finches differ in their plasma carotenoid levels? To answer this question, the researchers tested the following hypotheses:

H₀: m_M = m_F versus H_a: m_M ≠ m_F

What can we conclude at significance level 5%?

Reject the alternative hypothesis
Fail to reject the alternative hypothesis
Reject the null hypothesis

Researchers measured the amount of gray matter in the brains of 35 individuals. Gray matter is a major component of the nervous system, involved in many processes including muscle control, sensory perception, emotions, and decision making. In order to determine the link between intelligence and social circle size, they then recorded the number of Facebook friend each subject had. The scatterplot below shows the relationship between these two variables along with the least squares fit. Round all calculated results to...

Researchers equipped random samples of 46 male and 58 female students from a large university with a small device that secretly records sound for a random 30 seconds during each 12.5-minute period over two days. Then they counted the number of words spoken by each subject during each recording period and, from this, estimated how many words per day each subject speaks. The female estimates had a mean of 16,177 words per day with a standard deviation of 7520 words...

Researchers measured the cholesterol levels in mg per 100 mL for 50 participants. The participants were randomly selected from two age groups: under 50 years, or 50+ years. 1. What is the variable of interest being measured? 2. What type of sampling method is being used here? 3. Are there any possible confounding variables, or other sources of variability? The 50 participants are asked to change their diet to measure the effect it may have on lowering cholesterol levels. The...
