Hypothesis Test Sample Evidence
eBook (PDF): \$5.99     "Calculate the test statistic and p-value for each sample. Use Appendix below to calculate the p-value. Suppose you always reject the null hypothesis, regardless of any sample evidence. What is... More > the probability of Type I error? "< Less
Confidence Interval and Hypothesis Testing for Proportion
eBook (PDF): \$5.99     "1. Estimate the 95% confidence interval for the proportion of the electorate that support this policy 2. Given the politician’s requirement to support the policy, use a 5% significance... More > test to demonstrate whether or not he/she should support it. "< Less
Hypothesis Test Using Paired Observations
eBook (PDF): \$5.99     The amount of income spent on housing is an important component of the cost of living. The total costs of housing for homeowners might include mortgage payments, property taxes, and utility costs... More > (water, heat, electricity). An economist selected a sample of 20 homeowners in New England and then calculated these total housing costs as a percent of monthly income, five years ago and now. The information is reported below. Is it reasonable to conclude the percent is less now than five years ago?< Less
Hypothesis Testing for Mean with Known Population Standard Deviation
eBook (PDF): \$5.99     "A fast food restaurant strives to serve 80 customers per hour during its peak lunch hour. It samples 30 shifts (i.e. 30 peak lunch hours) to determine whether it is meeting this expectation. ... More > The sample mean is 75 customers. The population standard deviation is known to be 10. 1. Set up a null and alternative hypothesis to test whether this sample is falling below expectations. 2. Conduct this hypothesis test at the 5% level of significance. "< Less
Hypothesis Testing and Confidence Interval for Mean using t Distribution

The Health Authority is worried that if the mean days absent in either... More > clinic reach 20 days, it will have difficulties safely operating the clinics. Conduct separate hypothesis tests for Clinics A and B (at 95% confidence) that demonstrate whether they can be confident that absence is less than 20 days. "< Less
Single Proportion and Hypothesis Testing of Equality of two Means.

(This is called “recidivism.”) After a special government program... More > intended to reduce recidivism is put in place, a sample of 100 young offenders enrolled in the program reveals that 70 subsequently committed another crime. You are asked to make a judgment about whether the government funds invested in this program have succeeded in reducing crime. a. State the null and alternative hypotheses. b. Compute the value of the test statistic. c. Taking alpha=.01, conduct a hypothesis test using the p-value method. "< Less
Designing Hypothesis Tests for Digital Image Matching
eBook (PDF): \$5.00     This work describes a decision theoretic approach for the design of image matching techniques. Theoretically optimal matching algorithms are developed from first principles and analyzed using Monte... More > Carlo simulation. Practical methods are then proposed for reducing computation and improving performance when the image data deviates from the ideal model.< Less
