Chapter 8: Q 8.62 (page 331)

The margin of error is also called the maximum error of the estimate. Explain why.

Short Answer

Expert verified

This is because margin of error is estimating the mean of population by sample mean.

Step by step solution

01

Given Information

We are given with margin of error. We need to state why it is referred to as maximum error of estimate.

02

Explanation

For the given confidence level, estimating the mean of population by given sample mean is called margin of error.

Mathematically,

E=za2蟽n

Therefore, the margin of error is greater of the maximum error of the estimate.

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)

Suppose that you have obtained data by taking a random sample from a population and that you intend to find a confidence interval for the population mean, 渭. Which confidence level, 95% or 99%, will result in the confidence interval giving a more accurate estimate of 渭 ?

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

  • Lower confidence bound: x炉-t伪-s/蟺
  • Upper confidence bound: x^+t伪路s/n

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

Military Assistance Loans. The annual update of U.S. Overseas Loans and Grants, informally known as the "Greenbook," contains data on U.S. government monetary economic and military assistance loans. The following table shows military assistance loans, in thousands of dollars, to a sample of 10 countries, as reported by the U.S. Agency for International Development.

Smelling Out the Enemy. Snakes deposit chemical trails as they travel through their habitats. These trails are often detected and recognized by lizards, which are potential prey. The ability to recognize their predators via tongue flicks can often mean life or death for lizards. Scientists from the University of Antwerp were interested in quantifying the responses of juveniles of the common lizard to natural predator cues to determine whether the behavior is learned or congenital. Seventeen juvenile common lizards were exposed to the chemical cues of the viper snake. Their responses, in number of tongue flicks per twenty minutes, are presented in the following

Find and interpret a 90%confidence interval for the mean number of tongue flicks per 20minutes for all juvenile common lizards. Assume a population standard deviation of 190.0.
