Here are the population parameters of the bears: ?=207.6 ??? ?=96.6 ???

a) Using   this   data,   find   the   percentage   of   bears   that   weigh   between   180   and   220   pounds.





b) Find   the   weight   of   a   bear   for   the   90th   percentile.       Explain   what   this   means.




c) Is   the   weight   of   the   largest   bear   a   significant   weight?       Provide   evidence.

Expert Solution

Answer:

Given that

The population parameters of the bears: ?=207.6 ??? ?=96.6 ???

a) Using this data, find the percentage of bears that weigh between 180 and 220 pounds.

b) Find the weight of a bear for the 90th percentile. Explain what this means.

p-value for the bottom 90th percentile = 0.90

z-score for the p-vlue = 1.282

By applying normal distribution

c) Is the weight of the largest bear a significant weight? Provide evidence.

Yes,the weight of the largest bear is significant weight

p-value for the largest 99th percetile (Largest bear)= 0.99

z-score for the p-value =2.326

The value 2.326 is significanty high,since it is greater than 2

Among a population of 220 bears on a small island the frequency of the MC1R298Cys was 0.1 and the population was at Hardy Weinberg equilibrium. Then 30 black bears migrated to the small island from the mainland where the MC1R298Tyr was fixed. What are the new allele frequencies of the admixed population? Choose all the frequencies needed to complete the sentence. Among the admixed island population the f(MC1R298Tyr )= p= ______ and f(MC1R298Cys) = q= ________ , the new allele...

2. In terms of estimating population parameters using sample statistics, one would think that the highest level of confidence in an estimate (in other words, the 99% confidence level) would always be preferred by researchers. A. What is/are the advantage(s) of reporting a confidence interval at the 99% confidence level? B. Explain why researchers might rather choose a lower level of confidence (say the 95% or 90% confidence level) in their estimation of confidence intervals. Show all work, do not...

Researchers initiated a long-term study of the population of American black bears. One aspect of the study was to develop a model that could be used to predict a bear's weight (since it is not practical to weigh bears in the field). One variable thought to be related to weight is the length of the bear. The accompanying data represent the lengths and weights of 12 American black bears. Complete parts (a) through (d) below. (c) Determine the linear correlation...

Historically, weights of polar bears have been known to be Normally Distributed with a population mean...

Historically, weights of polar bears have been known to be Normally Distributed with a population mean of approx. 550 kg and a standard deviation of about 110 kg. Researchers are studying the effect of climate change on these animals; their hypothesis is that, because of the diminishing size of their feeding habitats, the average polar bear will be smaller than in the past. 1.) What is the probability that a randomly selected polar bear would weigh less than 480 kg?...

A population of bears contains 56 animals with black fur and 25 animals with brown fur. Black fur is the dominant trait. How would you calculate the frequency of the brown alleles (write out the equation(s) with the appropriate numbers as well as the answer)?

1. Null and alternative hypotheses are statements about A. population parameters. B. sample parameters. C. sample statistics. D. population statistics. E. It depends on the situation and the type of data has been collected. 2. A hypothesis test is conducted under the initial assumption that A. the alternative hypothesis is false. B. the alternative hypothesis is true. C. the null hypothesis is false. D. the null hypothesis is true. E. We never make any assumptions when conducting a hypothesis test....
