A simple random sample of 50 adults is obtained, and each person's red blood cell count (in cells per micro-liter) is measured. The sample mean is 5.23. The population standard deviation for red blood cell counts is 0.54. Use a 0.01 significance level to test the claim that the sample is from a population with a mean less than 5.4, which is a value often used for the upper limit of the range of normal values. What do the results suggest.
Draw the graph of the regression line on the same plot as the scatter diagram above.
The diameters of bolts produced by a certain machine are normally distributed with a mean of 0.30 Inches and a standard deviation of 0.01 inches.
Determine the most economical monthly shipping schedule. Provide a table showing the routes and total costs.
Conduct a hypothesis test using the .04 level of significance to determine if there is a difference between the population means.
Difference between the discrete and the continuous random variable.
Construct a scatter plot of P-RFM and P-HELM. If drawing the plot by hand, use graph paper to ensure accuracy.
Using the first two digits of the measurement as your stem, construct a stem and leaf display of the data above.
Steps in hypothesis test procedure - conducting a hypothesis test for some general statistic, ? say.
There are 6 children in a family. The number of children defines a population. The number of simple random samples of size 2 that are possible equals:
For a sample of 11 independent observations from a normal distribution of unknown μ and unknown variance σ 2 , the sample mean is 74.6 and sample variance is 2.2. What is the lower point of the 90% confidence interval for μ?
Determine for each variable if it is the explanatory variable, the response variable, or whether it could be both.
A 95% confidence interval for µ is found to be 652 ± 21.56 = ($630.44, $673.56). Determine which of the following statements is true.
