4) A credit card watchdog group claims that cardholders in California have more credit card debt than "cardholders in Florida. A random sample of 20 credit card holders from each state are selected. In California, the mean credit card debt was $3400 with a population standard deviation, 0, $950. In Florida, the mean credit card debt was $2900 with a population standard deviation, 62 = $850. Can you support the group's claim? Use a = 0.05. a. Identify the null...

According to a money report by a government institution, 18-to-20-year-old college students have an average credit card balance of $569. A researcher wants to find out if this number is lower now and collects data for a random sample of 40 college students. Their average credit card debt was found to be $542 with a sample standard deviation of $67.21. Complete parts a through b. a.) Using alphaα=.05, does this sample provide enough evidence to conclude that the average credit...

An economist claims that 40% of Americans older than 65 work part time. A sample of 200 Americans older than 65 showed 100 worked part time. Can you prove, at 95% confidence, that the economist’s claim is not true? Before doing the problem, you must show that the problem meets the requirements for performing the test. To get full credit, state your null and alternate hypothesis, show how you calculated your test statistic, show your critical region (reject region), and...
