If you want to be 95% confident of estimating the population proportion to within a sample error of +and - .05 and there is historical evidence that the population is approximately .35, what sample size is needed.
1.which of the following would have a binomial distribution?a.a couple will have children until they have three girls
This problem has to do with graphical plotting and computation for certain distribution. Please mention a detailed response to the questions listed with appropriate graphical and statistical data representation(s).
The data below shows the time to process an inpatient admission, before and after a system usage training session was given. The following hypotheses were formulated for this study.
Is there evidence that the population mean amount is different from 8.17 ounces? (Use a 0.05 level of significance.)
If a technical breakthrough occurred that raised the profit per unit of X 1 to $3, would this affect the optimal solution?
Find the z score corresponding to a score of X = 60 for each of the following distributions:
the weight of a product is normally distributed with a standard deviation of 1.0 ounces. what should the average weight
the weights of cats at a shelter are normally distributed with a mean of 11 lbs. and a standard deviation of 12. if 16
the following data are from an independent-measures experiment comparing two treatment conditions. do these data
If the average importance were computed for each group, would you expect the sample means to be similar or different? What was the total sample size in this study?
How many students would you include in a random sample to determine with 95% probability and to within 5% of the true value the proportion who arrive at 9am lectures without breakfast?
