Why is the coefficient of correlation an important tool for statisticians? Provide some specific examples from real life.
Scores on a test are normally distributed with a mean of 60.9 and a standard deviation of 12. Find P81, which separates the bottom 81% from the top 19%.
Your population mean has always been 9 customers per hour. The sample standard deviation is 4. The sample size is 25. The sample mean is 8.
Use the Internet to find a website that shows an example or application correlation or regression in the area of your interest or in your profession. Discuss how correlation or regression was used and summarize your finding.
x1, x2, x3 are zero mean Gaussian random variables with STD=4. Let x1 and x2 be independent and x3= a*x1+b*x2. Find the constants “a” and “b” such that the correlation between x1 and x3 is 0.3. What is the correlation between x3 and x2?
A retailer wants to estimate with 99% confidence the number of people who buy at his store. A previous study showed that 15% of those interviewed had shopped at his store.
In a recent survey, 10 percent of the participants rated Pepsi as being "concerned with my health." PepsiCo's response included a new "Smart Spot" symbol on its products that meet certain nutrition criteria
Find a value of p such that when 10,000 bits are received, the expected number of errors is at most 10 and Compute E(U(X)) and note for which values of k this converges. What property does U have for these values of k.
Determine the expected shape of distribution of sample mean? Compute the likelihood of choosing a sample with mean of at least $112,000?
Write the null and alternative hypotheses and calculate the test statistic, determine the critical value whether or not there has been an improvement.
The researcher then records the level of activity for each child during a 30 minute session on the playground. Is this an experimental or a correlation study? Explain your answer.
How much variability will you have if you predict sales with this model?
Suppose that the service rate to a waiting line system is 10 customers per hour (exponentially distributed).
