Understanding Birth Weights of Pandas: Importance and Data Analysis

Pandas are an endangered species, and each new birth is crucial for their conservation. This study provides statistical analysis of infant panda birth weights, using confidence intervals to estimate weights. We found that at a 95% confidence level, a panda at birth weighs between 2.48 lbs and 3.92 lbs, which is essential information for zoologists and wildlife preservation efforts. By understanding these weights, we can better assess the health of panda infants, ensuring they thrive in their natural habitats or receive necessary human care if needed.

  1. Panda Weights at Birth

  2. Why We Chose Pandas… • Pandas are an endangered species, and every panda that is born is an important addition to the population. • A panda birth is big news, and zoos gain a lot of publicity from them. • And they’re cute.

  3. Sample Data

  4. 94% Confidence Interval • CL=94% • D.O.F=n-1(13-1)=12 • E=tα/2*s/√n X-E <µ< X+E =2.175*1.2/ √13 3.2 -.724< µ< 3.2+ .724 =.724 2.48< µ<3.92 • We can be 94% confident that an infant panda at birth will weigh between 2.48 lbs and 3.92 lbs.

  5. 95% Confidence Interval • CL=95% • D.O.F=n-1(13-1)=12 • E=tα/2*s/√n =2.16*1.2/ √13 =0.718 • X-E<µ<X+E • 3.2-.72<µ<3.2+.72 • 2.48< µ<3.92 We can be 95% confident that an infant panda at birth will weigh between 2.48 lbs and 3.92 lbs.

  6. 98% Confidence Level • CL=98% • D.O.F=n-1(13-1)=12 • E=tα/2*s/√n • =1.356*1.2/ √13 =.4513 X-E <µ< X+E 3.2 -.4513< µ< 3.2+.4513 2.75< µ<3.65 We can be 98% confident that an infant panda at birth will weigh between 2.75 lbs and 3.65 lbs.

  7. 99% Confidence Level • CL=99% • D.O.F=n-1(13-1)=12 • E=tα/2*s/√n • =3.06*1.2/ √13…=1.02 • X-E <µ< X+E • 3.2 -1.02< µ< 3.2+ 1.02 2.18< µ<4.22 We can be 99% confident that an infant panda at birth will weigh between 2.18 lbs and 4.22 lbs.

  8. Summary • We chose this data because we feel it is important that every creature deserves an equal chance here on Earth. • A confidence interval is a range of values used to estimate the true value of a population parameter. Since it is impossible to know the exact number in a population, using a confidence interval is the most accurate choice. • For our line of data, the 95% confidence interval is the most helpful when determining the actual birth weights of infant pandas. • This data can be used by zoologists and wildlife preservers to determine whether or not a panda is healthy after birth. This will determine if the infant is well enough to live in the wild with its mother or if it needs human support in order to live.
