Create an equation for which the appropriate test of the statistical hypothesis would require the use of a z-score. (For the population mean for the variable of interest, you may invent a hypothetical population mean for the sake of this equation.)
o Clearly identify the independent and dependent variables you would analyze.
o Determine whether a one-tail or two-tail test is most appropriate and explain why.
o Generate a testable null statistical hypothesis and an alternative statistical hypothesis.
o Select an alpha level of .05, .01, or .001 and justify your choice.
Sample mean is 50, t-statistic is 1.96, and standard error of sample mean is 2. Determine the 95 percent confidence interval?
Electronic baseball games manufactured by Tempco Electronics are shipped in lots of 25. Before shipping, a quality control inspector randomly selects a sample of 6 from each lot for testing. If sample contains any defective games, the entire lot i..
Conduct a hypothesis test using the .04 level of significance to determine if there is a difference between the population means.
The sample mean is 50, the t-critical value is 1.96, and the standard error of the sample mean is 2.
Use a significance level of alpha = .05 to test the claim that p > .5. The sample is a simple random sample n = 50. Show how to calculate beta for the test and assume the true population proportion is .6.
Find the probability that a randomly selected employee earns less than $5.43.
For testing the null hypothesis at the 4% level of significance that mu GE 100 vs the alternative that mu
The following frequency table determine the ages of 100 shoppers at the local grocery store. Compute the sample mean for this data (mean for the grouped data).
Suppose that 55 percent of the people in a population of 500,000 support your candidate. If you conduct a poll of 1,000 people, what is the interval that has a 95 percent chance of containing the results of your poll?
A randomized block design with 4 treatments and 5 blocks produced the following sum of squares values: SST = 1951, SSTR = 349, SSE = 188. The value of SSB must be:
Four brands of lightbulbs are being considered for use in the final assembly area of the Saturn plant in Spring Hill, Tennessee. The director of purchasing asked for samples of 100 from each manufacturer.
As part of this trial, they want to find out whether there is a difference between effectiveness for women and for men. At = .05, what is the test value?
