Chapter 8: Q 8.41 (page 330)

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 ?

Short Answer

Expert verified

Confidence level of 95%will estimate population mean more precisely.

Step by step solution

01

Given Information

Data is obtained by taking a random sample from population. Two confidence intervals of value95%,97%are available to measure population mean.

02

Explanation

As we know that larger confidence level results in larger confidence interval of 渭.

Hence, for 99%confidence interval, we will obtain 渭of smaller length as compared to that of 99%.

Therefore the estimation of population mean is better in case of 95%as compared to99%.

The margin of error can be determined if you know only the confidence level, population standard deviation, and sample size.

For a t-curve with df=8, find each t-value, and illustrate your results graphically.

b. t0.10

c. The t-value having area 0.01 to its left (Hint: A t-curve is symmetric about 0

d. The two t-values that divide the area under the curve into a middle 0.95 area and two outside 0.025 areas

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.

The confidence level can be determined if you know only the margin of error.
