Assuming you are dealing with a finite statistical population of lemmings,
whose parametric mean is estimated at 63.5 g and the parametric variance at 148.84
g2.

4. What would be the probability of randomly selecting, in this population, individuals
weighing less than 41.0 g?
5. What would be the probability of randomly selecting, in this population, an individual
whose weight would be between 60.0 and 70.0 g?

6. What is the probability, still in this population, that an individual weighs between
50.0 and 60.0 g?
7. What would be the standard deviation of the average of all possible samples of 10
elements taken from this population?

When should you use non-parametric tests of statistical significance? When is it inappropriate to use non-parametric statistical tests? Describe what is meant by the phrase: "Power of a a statistical test". Are non-parametric statistical procedures as powerful as parametric statistical procedures?

Consider a finite population of size N in which the mean of the variable of interest Y is u. Suppose a sample of size n is taken from this population using simple random sampling with replacement. Suppose that the sample mean Y is used to estimate u. (a) [3 marks] Calculate the probability of sample and probability of inclusion for this sam- pling protocol. (b) (4 marks] Show that Y is unbiased for u. (c) [4 marks] Calculate Var(Y). Make...

Assuming that the population is normally distributed, construct a 99% confidence interval for the population mean,...

Assuming that the population is normally distributed, construct a 99% confidence interval for the population mean, based on the following sample size of n=7. 1, 2, 3,4, 5, 6,and 30 Change the number 30 to 7 and recalculate the confidence interval. Using these results, describe the effect of an outlier (that is, an extreme value) on the confidence interval. Find a 99 % confidence interval for the population mean. (Round to two decimal places as needed.) Change the number 30...

Assuming that the population is normally distributed, construct a 9090% confidence interval for the population mean for each of the samples below. Explain why these two samples produce different confidence intervals even though they have the same mean and range.
