Nursing QUESTION #9203
Question 2261
A researcher reports Type II error (\(\beta\) error) in a clinical study. What does this mean for nursing practice?
  • A false positive result was reported — treatment appears effective when it is not
  • A true effect was missed — the study concluded no difference when one actually exists✔️
  • The sample size was too large, inflating statistical power
  • The p-value was below the significance threshold incorrectly
Correct Answer Logic:
Correct Answer: B

Statistical Errors in Hypothesis Testing:
ErrorAlso CalledMeaningRisk
Type I (\(\alpha\))False PositiveRejecting \(H_0\) when it is actually trueAdopting ineffective treatment
Type II (\(\beta\))False NegativeFailing to reject \(H_0\) when it is actually falseMissing an effective treatment
Statistical Power \(= 1 - \beta\) = probability of correctly detecting a true effect.

In nursing, a Type II error could mean a beneficial intervention is dismissed and patients miss out on better care. Increasing sample size is the main way to reduce \(\beta\) and increase power.

Journalism / Mass Communication QUESTION #6357
Question 2264
According to the textbook, the FIRST regular English-language newspaper was published in which year and city?
  • London, 1605
  • Boston, 1690
  • London, 1621✔️
  • Paris, 1631
Correct Answer Logic:

There is considerable debate about what constitutes the world's “first” newspaper. The World Association of Newspapers recognises Relation (France, 1605) as the first newspaper. However, the first titled English-language private newspaper was The Corrant, published in London in 1621. The first American newspaper was Publick Occurrences, published in Boston in 1690, though it was suppressed after a single issue by colonial authorities. The first English daily newspaper was the Daily Courant, founded by Samuel Buckley on 11 March 1702. The question asks for “first regular English-language newspaper” — this refers to The Corrant, London, 1621. Students must carefully distinguish between the first French newspaper (La Gazette, 1631), the first American newspaper (Publick Occurrences, Boston, 1690), and the first English daily (Daily Courant, 1702).

Question 2271
Climate-smart agriculture (CSA) is defined by FAO as an integrated approach that simultaneously addresses three objectives. Which correctly identifies all three pillars?
  • Maximizing synthetic input use, eliminating smallholder farming, and industrializing food systems
  • Sustainably increasing agricultural productivity and incomes (food security), adapting and building resilience to climate change (adaptation), and reducing greenhouse gas emissions where possible (mitigation) — with food security as the primary priority✔️
  • Exclusively reducing agricultural GHG emissions regardless of impact on food security
  • Promoting organic farming, eliminating livestock, and rewilding agricultural land
Correct Answer Logic:
FAO's CSA framework has three pillars: (1) Productivity — sustainably increasing agricultural output and farmer incomes to achieve food security; (2) Adaptation — reducing vulnerability and building resilience to climate shocks; (3) Mitigation — reducing GHG emissions per unit food produced and sequestering carbon in soils/biomass. The three objectives must be pursued together, with explicit recognition of trade-offs, particularly between mitigation and food security for vulnerable smallholders.
