You want to obtain a sample to estimate a population proportion. At this point in time, you have no reasonable estimate for the population proportion. You would like to be 99% confident that you esimate is within 3% of the true population proportion. How large of a sample size is required?
Do teachers find their work rewarding and satisfying? An article reports the results of a survey of 399 elementary school teachers and 261 high school teachers. Of the elementary school teachers, 224 said they were very satisfied with their jobs, whereas 121 of the high school teachers were very satisfied with their work. Estimate the difference between the proportion of all elementary school teachers who are satisfied and all high school teachers who are satisfied by calculating a 95% CI. (Use Pelementary - Phigh school. Round your answers to four decimal places.) USE SALT
Imagine that the figure below represents two means with their respective 95% Cls in a paired design. Either use this information to estimate the (approximate) p-value or explain why this is not possible.
A sample proportion is calculated from a sample size of 132. How large of a sample would we need in order to decrease the standard error by a factor of 9?
Determine the number of samples you will choose from a population of 5,200 considering that you assigned a 5% margin of error.
Using the traditional formula, a 95% CI for P₁ - P₂ is to be constructed based on equal sample sizes from the two populations. For what value n (= m) will the resulting interval have width at most 0.2 irrespective of the results of the sampling? (Round your answer up to the nearest whole number.) n = You may need to use the appropriate table in the Appendix of Tables to answer this question.

A logging company wants to calculate the total amount of volume in cubic meters of wood, in logs that can be extracted from a eucalyptus forest. The perimeter of the log is easy to obtain, but the height is difficult to measure. Not even with the use of an appropriate instrument is it possible to measure because the trees are too close to each other. The forestry engineer in charge decides to try a sampling estimate. The idea is to measure the trunk perimeter and height (until the beginning of the branch) of 13 randomly selected trees and extend the result obtained to all 2000 trees in the forest. It is known that there is a constant relationship between the height (Y) and the perimeter of the trunk (X) of the tree. Thus, the engineer proposes that 13 trees with trunks of different perimeters be selected and their heights measured. Next, he proposes to fit a linear regression model to the data obtained yi = a + bxi + ei. The model will provide a value that establishes the relationship…
The control department of a light bulb manufacturer randomly picks 4400 light bulbs from the production lot every week. The records show that, when there is no malfunction, the defect rate in the manufacturing process (due to imperfections in the material used) is 1% . When 1.5% or more of the light bulbs in the sample of 4400 are defective, the control unit calls repair technicians for service. Answer the following. (If necessary, consult a list of formulas.) (a)Find the mean of p , where p is the proportion of defective light bulbs in a sample of 4400 when there is no malfunction. (b)Find the standard deviation of p . (c)Compute an approximation for P≥p0.015 , which is the probability that the service technicians will be called even though the system is functioning properly. Round your answer to four decimal places.
