1. Provide an example of an application of the normal distribution.
2. Explain why standard normal distribution can be used to find the probabilities for all normal distributions?
3. I need an example of binomial experiment.
Find the standard deviation and variance from the (population) data below. Describe your results.
The probability of an randomly selected person quits a team is 0.125. Assume the team has n members. Determine the smallest n that the team needs to have if the probability of the team has at least 20 members left is 0.9.
Marentette and El-Masri (2011) used logistic regression to identify predictors of obtaining seasonal influenza vaccination among hospital-based nurses in Canada. Their results are shown in table 1:
The main goal of correlation research is ______________

To forcast the sample size within 0.02 with 90 percent confidence. The CEO of the organization needs to forcast the proportion of Canadians who own their house.
The weekly salaries of teachers in one state are normally distributed with mean of $490 and standard deviation of $45. Determine the probability that a randomly selected teacher earns more than $525 per week?
Calculate the control limits for a c chart when Ubar = 3.0%, n = 60, and you collect one sample per hour for 40 hours of production. (2 sets of control limits required, x bar and range)
Let A be the event that a randomly chosen employee has a college degree and B the event that the chosen employee's income is more than $50,000.
Use the study to estimate the risk of an air bag fatality on a child seated on the front passenger seat.
Consider the following estimated regression equation, based on 10 observations.
Describe why the normal distribution can be used as an approximation to binomial distribution. What conditions should be met to use the normal distribution to approximate the binomial distribution? Why is a correction for continuity essential.
