Chapter 8: Q 8.7 (page 319)

A simple randoes sample is taken from a population and yields the following data for a variable of the population:

Find a point estimatate for the population mean.(i.e, the mean of the variable)

Short Answer

Expert verified

The point estimatate for the population mean is 23

Step by step solution

01

Step 1:Given information

02

Step 2:Simplification

The mean of the variable is

x炉=鈭�xin=9+32+37+32+20+24+10+15+21+3010=23010=23

Therefore,the point estimatate for the population mean is 23

Positively Selected Genes. R. Nielsen et al. compared 13.731 annotated genes from humans with their chimpanzee orthologs to identify genes that show evidence of positive selection. The researchers published their findings in "A Scan for Positively Selected Genes in the Genomes of Humans and Chimpanzees" (PLOS Biology, Vol. 3, Issue 6. Pp. 976-985). A simple random sample of 14 tissue types yielded the following number of genes.

Poverty and Dietary Calcium. Refer to Exercise 8.70.

a. Find a 90%confidence interval for 渭.

b. Why is the confidence interval you found in part (a) shorter than the one in Exercise 8.70?

c. Draw a graph similar to that shown in Fig8.6 on page 326 to display both confidence intervals.

d. Which confidence interval yields a more accurate estimate of 渭? Explain your answer.

Explain the effect on the margin of error and hence the effect on the accuracy of estimating a population mean by a sample mean.

Increasing the confidence level while keeping same sample size.

One-Sided One-Mean z-Intervals. Presuming that the assumptions for a one-mean z-interval are satisfied, we have the following formulas for (1-伪)-level confidence bounds for a population mean \(\mu\) :

- Lower confidence bound: x~-z蟽路蟽/n

- Upper confidence bound: x炉+z伪路蟽/n

Interpret the preceding formulas for lower and upper confidence bounds in words.

Assume that the population standard deviation is known and decide weather use of the z-interval procedure to obtain a confidence interval for the population mean is reasonable. Explain your answers.

The variable under consideration is very close to being normally distributed, and the sample size is 10.
