Chapter 8: Q 8.5. (page 319)

Suppose that you take 1000simple random samples from a population and that, for each sample, you obtain a 95% confidence interval for an unknown parameter. Approximately how many of those confidence intervals will contain the value of the unknown parameter?

Short Answer

Expert verified

There are approximately 950confidence intervals that will contain the value of the unknown parameter.

Step by step solution

01

Given informataion

The simple random samples are: 1000.

The confidence interval for unknown parameter is:95%.

02

Simplification

We will find the confidence intervals that will contain the unknown parameter's value.

95%of1000=95100×1000=95×10=950.

Therefore, approximately 950confidence intervals are there which will contain the value of the unknown parameter.

Toxic Mushrooms?Cadmium, a heavy metal, is toxic to animals. Mushrooms, however, are able to absorb and accumulate cadmium at high concentrations. The Czech and Slovak governments have set a safety limit for cadmium in dry vegetables at 0.5part per million (ppm). M. Melgar et al. measured the cadmium levels in a random sample of the edible mushroom Bolefus pinicola and published the results in the paper "Influence of Some Factors in Toxicity and Accumulation of Cd from Edible Wild Macrofungi in NW Spain (Journal of Envionmental Science and Health. Here are the data obtained by the researchers.

Find and interpret a 99%confidence interval for the mean cadmium level of all Boletus pinicola mushrooms. Assume a population standard deviation of cadmium levels in Bolefus pinicola mushrooms of 0.37ppm.

When estimating an unknown parameter, what does the margin of error indicate?

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.

Poverty and Dietary Calcium. Refer to Exercise 8.70

a. Determine and interpret a 95%upper confidence bound for the mean calcium intake of all people with incomes below the poverty level.

b. Compare your one-sided confidence interval in part (a) to the (twosided) confidence interval found in Exercise 8.70

A confidence interval for a population mean has a length of 162.6.

a. Determine the margin of error.

b. If the sample mean is 643.1, determine the confidence interval.

c. Construct a graph that illustrates your results.
