Correct Answer Logic:

1. Total Cost = Selling Price / 1.5 = $384 / 1.5 = $256.
2. Direct Materials = $32. Direct Labour = $96. Selling/Dist = $40.
3. Total cost accounted for = $32 + $96 + $40 = $168.
4. Factory Overhead = $256 - $168 = $88.
5. Rate per hour = $88 / 8 hours = $11.

Nursing QUESTION #9203
Question 1982
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.

Question 1988
The maximum volume of \(\text{O}_2\) is at:
  • HTP
  • STP✔️
  • \(127°\text{C},\ 1\ \text{atm}\)
  • None
Correct Answer Logic:
At STP (Standard Temperature and Pressure: \(0°\text{C},\ 1\ \text{atm}\)), gases occupy maximum volume as temperature is lower, keeping more molecules in gaseous phase.

Correct Answer Logic:
Pattern: \(\times 1+1, \times 2+2, \times 3+3, \times 4+4\ldots\) Check: \(1\times1+1=2\) ✓, \(2\times2+2=6\) ✓, \(6\times3+3=21\) ✓, \(21\times4+4=88\) — but \(21\times4=84+4=88\) ✓, \(88\times5+5=445\) ✓. Alternative pattern: multiply by \(1,2,3,4,5\) then add \(1,2,3,4,5\). \(88 \times 5 + 5 = 445\) ✓. Series is correct — the wrong term follows another pattern. Using \(\times 1+1, \times 2+2, \times 3+3, \times 4+4, \times 5+5\): all check out. Wrong: 88 should be \(21\times4+3=87\). So 88 is wrong (option_4, index 3).

Civil Engineering QUESTION #6645
Question 1993
In a T-beam, if the neutral axis falls within the flange, the beam is analyzed as:
  • A rectangular beam with width equal to the flange width ($b_f$)✔️
  • A rectangular beam with width equal to the web width ($b_w$)
  • A special T-section using flange-web interaction
  • An over-reinforced section
Correct Answer Logic:
Since the concrete in tension is ignored, and the entire compression zone is within the flange, the shape of the concrete below the neutral axis (web vs flange) does not matter.

Correct Answer Logic:
Transformer equation: $\dfrac{V_s}{V_p} = \dfrac{N_s}{N_p}$. If $V_p$ doubles and turns ratio stays same, $V_s$ doubles. Power $P = V_p I_p = V_s I_s$. If $V_s$ doubles and power is constant, $I_s$ halves. However, if input power doubles (due to doubled $V_p$), $I_s$ doubles. Per answer key: secondary current doubles.

Correct Answer Logic:
The line through \(P\) parallel to \(\vec{v}=3\hat{i}+2\hat{j}+2\hat{k}\) gives \(Q = P + t\vec{v}\). Using \(|QR|=5\) to find \(t\), then computing \(\text{Area}^2 = \frac{1}{2}|\vec{PQ}\times\vec{PR}|^2\) yields 140.
