A census is a ________________ of an entire population
A restaurant claims that its speed of service time is less than 18 minutes. A random selection of 36 service times was collected, and their mean was calculated to be 17.7 minutes. Their standard deviation is 3.1 minutes. Is there enough evidence to support the claim at alpha = .08. Use the p-value. (Hint: first show Ho and Ha. Then calculate the proper test statistic, use the table or Excel to get the P-value)
Determine the minimum required sample size if you want to be 99% confident that the sample mean is within 2 units of the population mean given sigma = 7.8. Assume the population is normally distributed.
Two fair six-sided dice are tossed independently. Let X be value of first die, and Y value of second. Find out the expectations of following random variables.
For each of the following situations, indicate the appropriate measure, incidence rate or prevalence rate and the numerical value of the rate.
In the study of age and systolic blood pressure of five randomly selected subjects, a researcher reported the following data.
Illustrate that probability distribution of X satisfies properties of a discrete probability distribution.
Determine point estimate of population mean? By using 90% confidence, determine the margin of error?

Consider the following time plot of the values of variable Y for each month of a 60-month period. This plot displays
Make an interval estimate the population means score for the daycare children so that you are 95% confident that the true mean is in your interval.
Which test do we use to see if the difference in our sample is statistically significant? Why? Should it be one or two-tailed?
Additionally, student should use graphing function to graph data and calculate regression equation.
Calculate separately for 1983 and 1987, the 95% confidence interval for the proportion of students who had driven an automobile while drinking.
