Population with unknown parameters
The following sample was obtained from population with unknown parameters. Scores: 8, 12, 7, 3, 9
a. Compute the sample mean and standard deviation.
b. Compute the estimated standard error for M.
Expected delivery within 24 Hours
If the size of sample equals the size of the population, we would not expect any error in estimating the population parameter.
An estimate of the population mean based upon a large sample is less reliable than an estimate made using a small sample.

To evaluate the effect of a treatment, a sample of n = 16 isd from a population with a mean of µ = 42, and the treatment is administered to the individuals in the sample. After treatment, the sample mean is found to be M = 35.
A researcher conducts independent-measures study comparing two treatments as well as reports the t statistic as t(28) = 2.039.
Employ the value of the linear correlation coefficient r to determine the coefficient of determination and the percentage of the total variation that can be explained by the linear relationship between the two variables. R=0.1
Assume IQ scores were obtained from randomly chosen sibling. For 20 such pairs of people, the linear correlation is 0.917 and equation of the regression line is y=6.44+0.94x, where x shows IQ score of the younger child.
