Assignment Solutions

This paper addresses six statistical questions focusing on normal distributions using options available in Excel, as well as a reflection paper on the importance of leadership in diversity and inclusion in the field of human resources (HR). Each question will be addressed systematically.

Question 1: Bone Density Test

Problem: To find the probability that a randomly selected subject has a bone density score between -1.03 and 2.01 under a standard normal distribution.
Approach:
1. Understanding Standard Normal Distribution: The standard normal distribution has a mean (µ) of 0 and a standard deviation (σ) of 1.
2. Using Excel: We will use the `NORM.DIST` function to calculate cumulative probabilities for -1.03 and 2.01.
- Probability for Z=-1.03: `=NORM.S.DIST(-1.03, TRUE)=0.1511`
- Probability for Z=2.01: `=NORM.S.DIST(2.01, TRUE)=0.9785`
3. Calculating the Probability:
\[
P(-1.03 < Z < 2.01) = P(Z < 2.01) - P(Z < -1.03) = 0.9785 - 0.1511 = 0.8274
\]
Thus, there is an 82.74% probability that the bone density score lies between -1.03 and 2.01.

Question 2: U.S. Airforce Pilots’ Height Requirement

Problem: Calculate the percentage of women whose heights are between 62 inches and 76 inches.
Approach:
1. Given Parameters:
- Mean (µ) = 63.8 inches
- Standard Deviation (σ) = 2.9 inches
2. Z-scores Calculation:
- For 62 inches:
\[
Z = \frac{62 - 63.8}{2.9} = -0.62
\]
- For 76 inches:
\[
Z = \frac{76 - 63.8}{2.9} = 4.05
\]
3. Excel Calculations:
- Probability for Z=-0.62: `=NORM.S.DIST(-0.62, TRUE) = 0.2659`
- Probability for Z=4.05: approx. 1 (due to very high Z-score)
4. Conclusion:
\[
P(62 < X < 76) = P(X < 76) - P(X < 62) = 1 - 0.2659 = 0.7341
\]
Thus, 73.41% of women meet the height requirement.

Question 3: Cumulative Area to the Left of Z=-0.18

Problem: Find the cumulative area from the left under the curve for a z-score of -0.18 and the area to the right.
Approach:
1. Z-score: -0.18
2. Using Excel:
- For cumulative area to the left: `=NORM.S.DIST(-0.18, TRUE) = 0.4286`
- For cumulative area to the right:
\[
P(X > -0.18) = 1 - P(X < -0.18) = 1 - 0.4286 = 0.5714
\]
Thus, the area to the left is 42.86%, and to the right is 57.14%.

Question 4: Finding Z-score from Right Area

Problem: Finding the z-score corresponding to an area of 0.6630 from the right.
Student's Error: They used `=NORM.S.INV(0.6630)` directly, arriving incorrectly at a z-score of 0.42.
Correction Steps:
1. Understanding Areas: Since the result gives an area from the right, we need to find the left cumulative probability.
\[
P(X < Z) = 1 - P(X > Z) = 1 - 0.6630 = 0.3370
\]
2. Using Excel:
- Correct formula: `=NORM.S.INV(0.3370)` which gives a z-score of approximately -0.42.

Question 5: Microearthquakes and Richter Scale

Problem: What percentage of earthquakes are classified as microearthquakes (magnitude < 2.00)?
Approach:
1. Given Parameters:
- Mean (µ) = 1.192
- Standard Deviation (σ) = 0.615
2. Z-score Calculation:
\[
Z = \frac{2.00 - 1.192}{0.615} = 1.314
\]
3. Calculating Probability:
- Using Excel: `=NORM.DIST(2.00, 1.192, 0.615, TRUE)` yields approximately 0.9051.
4. Conclusion: Thus, about 90.51% of earthquakes are considered microearthquakes.

Reflection Paper on Leadership in Diversity and Inclusion

Part 1: Rationale for the Importance

The significance of leadership in Diversity and Inclusion (D&I) for HR professionals cannot be overstated. Effective D&I leadership fosters an environment where employees feel valued regardless of their backgrounds. This enhances engagement and productivity, benefiting organizational culture and innovation (Roberson, 2006). Furthermore, as workplaces become increasingly diverse, HR practitioners must lead initiatives that transcend discriminatory practices, ensuring equitable treatment for all employees (Cox, 1991).

Part 2: Relevance to Career and Industry

In my journey through HR, I have witnessed how D&I strategies can impact team dynamics and performance. My past roles emphasized leveraging diverse talents to foster creativity, which prepared me for advocacy and support roles in such initiatives. As I aim for leadership positions in HR, a deep understanding of the principles of D&I will be paramount, aligning with future industry trends that prioritize inclusionary practices (Shen et al., 2009).

Part 3: Empirical Research Connection

Cox and Blake (1991) outline a framework addressing why Diversity is essential to competitive advantage. Their study highlights how embracing diversity in leadership positions enhances decision-making and problem-solving capabilities. By linking this research to my personal experiences, I can derive meaningful insights. Leaders who embrace D&I encourage collaboration, leading to better problem-solving and overall organizational performance.

Conclusion

Addressing statistical problems involves understanding normal distributions and employing Excel effectively. Leadership in D&I within HR is not just a necessary initiative but also a critical success factor for organizations. The integration of research and personal experiences strengthens the case for proactive D&I leadership.
