Military radar and missile detection systems are designed to warn a country of an enemy attack. A reliability question is whether a detection system will be able to identify an attack and issue a warning. Assume that a particular detection system has a .90 probability of detecting a missile attack.
(A) What is the probability that a single detection system will detect an attack?
(B) If two detection systems are installed in the same area and operate independently, what is the probability that at least one of the systems will detect the attack?
(C) If three systems are installed, what is the probability that at least one of the systems will detect the attack?
(D) Would you recommend that multiple detection systems be used? Explain.
A report states that 40% of home owners had a vegetable garden. How large a sample is needed to estimate the true proportion of home owners who have vegetable gardens to within 4% with 95% confidence?
Two-liter plastic bottles used for bottling cola are shipped in lots of 100. Suppose the lots are 5 percent defective. Some bottles leak, some are too small, and so forth.
Let the random variable X denote the number of emergency calls received by the campus police office each day. The probability mass function of X is given by:
Test for single Proportion - Are the data consistent with the model? Answer yes or no, and explain briefly.
One advantage of the repeated measures ANOVA is that it eliminates "individual differences" as a source of variability. Explain why there are no individual differences in the numerator and in the denominator of the F ratio.
In some places in the US, people are aware of the need for more care for older citizens, like Dr. Hope. In the election in one area, they put forward a referendum that would increase the county sales tax by one cent to pay for increased services f..
The Kruskal-Wallis rank test is a nonparametric replacement - The Wilcoxon rank sum test tests a null hypothesis
If the Sum of Squares for Treatments (SST) is 10% of SS(Total), and the Sum of Squares for Blocks (SSB) is 20% of SS (Total), find the F values for this experiment.
What is the difference between the critical-value method and the p-value method of hypothesis testing? Include in your post how the question's topic pertains to your health discipline.
The random number generator on calculators randomly generates a number between 0 and 1. The random variable X, the number generated, follows a Uniform Probability Distribution. What is the probability of generating a number between 0 and 0.2?
A researcher has been hired by a pizzeria to determine which type of crust customers prefer. The restaurant offers three types of crust: hand tossed, thick, and thin.
Research has shown that losing even one night's sleep can have a significant effect on performance of complex tasks such as problem solving ( Linde & Bergstroem, 1992).
