The question describes a researcher assessing whether the true proportion of adults with diabetes in the United States in 2021 differs from a known figure from 2009 (9%). The scenario involves a single sample and a comparison to a known population proportion, which points toward a proportion-based hypothesis test. Option 1: One-sample t-test.

At the beginning of the semester, a professor hypothesizes that half of the class would think the pace of the class was ‘just right’. After collecting anonymous survey data from a random sample of the class, it was observed that 57% of the class though the pace was ‘just right’. What is the appropriate null hypothesis to determine if the true proportion of students who thought the pace was ‘just right’ differs from the hypothesized value?

A hypothesis test about the true proportion was performed using the following hypotheses, which yielded a p-value < 0.05 (suppose all conditions for inference are satisfied): 𝐻 0 : 𝑝 = 0.7 , 𝐻 𝑎 : 𝑝 < 0.7 Which of the following scenarios would yield a similar p-value (i.e., p-value < 0.05) as the initial hypothesis test above?

For developing countries in Africa and the Americas, let p1 and p2 be the respective proportions of babies with a low birth weight (below 2500 grams). Suppose we will test H0: p1 = p2 against H1: p1 > p2. If respective random samples of sizes n1 = 900 and n2 = 700 yield y1 = 135 and y2 = 77 babies with a low birth weight, what is the p-value associated with this hypothesis test.  (Give your answer to four decimal places.)

Researchers are studying whether a high-protein diet reduces mortality in lab mice exposed to a toxin. Among 900 mice on a standard diet, 36 died. Among 950 mice on a high-protein diet, 15 died. Definitions: p1 = proportion of mice that died on the standard diet p2 = proportion of mice that died on the high-protein diet Hypotheses: H0: p1 = p2 (The diet does not affect mortality; both groups have the same mortality rate) H1: p1 > p2 (The diet reduces mortality; mice on the standard diet have a higher mortality rate) What is your decision, and what does it mean in the context of the study?
