Questions: In the data table, the entries are for five different years and consist of the weights (metric tons) of lemons imported from another country and car crash fatality rates per 100,000 population. The data are based on data from a scientific publication. Considering the source of the data, does that source appear to be biased in some way? Lemon Imports 225 271 351 478 532 Crash Fatality Rate 16.2 16.1 14.5 15.1 15.1 Does the source appear to be biased? A. Yes, because a scientific journal would prefer that there is an association between lemon imports and car crash fatality rates. B. Yes, because a scientific journal is likely to collect or present the data in a way that is biased. C. No, because a scientific journal has no reason to collect or present the data in a way that is biased. D. Yes, because a scientific journal would prefer that there is no association between lemon imports and car crash fatality rates.

The answer is C: No, because a scientific journal has no reason to collect or present the data in a way that is biased.

Explanation for each option:

A. Yes, because a scientific journal would prefer that there is an association between lemon imports and car crash fatality rates.

  • This option is incorrect. Scientific journals aim to present data objectively and are not supposed to have a preference for any particular outcome. Their goal is to report findings based on empirical evidence, regardless of whether an association exists.

B. Yes, because a scientific journal is likely to collect or present the data in a way that is biased.

  • This option is incorrect. Reputable scientific journals follow strict peer-review processes and ethical guidelines to ensure that data collection and presentation are unbiased. Any bias would undermine the credibility of the journal.

C. No, because a scientific journal has no reason to collect or present the data in a way that is biased.

  • This option is correct. Scientific journals are committed to maintaining objectivity and integrity in their publications. They have no inherent reason to bias the data, as their primary goal is to advance knowledge based on accurate and reliable information.

D. Yes, because a scientific journal would prefer that there is no association between lemon imports and car crash fatality rates.

  • This option is incorrect. Similar to option A, scientific journals do not have preferences for specific outcomes. Their role is to publish findings based on the data, whether or not an association is found.

In summary, reputable scientific journals are designed to minimize bias and present data objectively, making option C the correct answer.

Question 23 Given the following budget constraints, where units of good 1 are measured on the horizontal axis and units of good 2 are measured on the vertical axis. A first budget line is provided and is labeled B1. It has a horizontal intercept defined by the ordered pair (100,0) and a vertical intercept defined by the ordered pair (0,100). Shifted to the left of the first budget line, a second budget line is provided and is labeled B2. This second budget line has a horizontal intercept defined by the ordered pair (100,0) and a vertical intercept defined by the ordered pair (0,50). Question: What explains the change in the budget constraint from B1 to B2? Preferences for good 2 decreased Preferences for good 1 increased The price of good 2 decreased Income decreased The price of good 1 increased The price of good 1 decreased Income increased The price of good 2 increased

In the autoimmune disease myasthenia gravis (MG), the body makes self-reactive antibodies against the acetylcholine receptor on the postsynaptic cell, which block or destroy the receptor. A normally functional ACh receptor binds acetylcholine, opening an ion channel and producing an EPSP, but this doesn't happen in MG, which decreases the likelihood of the muscle fiber reaching threshold depolarization and contracting, causing muscle weakness. Additional considerations: Acetylcholinesterase is an extracellular enzyme that breaks down ACh to acetate and choline in order to terminate its effect. Not all nAChR's will be destroyed by the body's immune system. Which of the following treatments would produce additional muscle strength in a person with MG? treatment with an antibody to acetylcholine treatment with acetylcholinesterase treatment with an inhibitory neurotransmitter treatment with an acetylcholinesterase inhibitor treatment with a Na+/ K+ ATPase inhibitor
