STATISTICS 2023 NAME, PRINT IN INK______________________________ FINAL EXAM SIGNATURE, IN INK_______________________________ FALL 2003 SS or OSU ID #, IN INK_____________________________ TRUE OR FALSE. Answer with a capital T or F. (3 points each) ______ 1. If the z score is -1.5 for an individual data value from a population with mean of 25 and standard deviation of 6 then the individual data value is equal to 16. ______ 2. Continuous random variables have probability only on specific values of the variables. ______ 3. The probability density function for the normal distribution is a left skewed distribution with only positive values. ______ 4. The point estimate for the population mean is the center of a confidence interval to estimate the population mean. ______ 5. The p-value in a hypothesis test is the tail area associated with the rejection region of the hypothesis test and is set by the researcher before the data are collected. ______ 6. The t-multiplier in the bound of error for a 99% confidence interval to estimate the mean of a population with unknown variance based on only 10 observations would be the value 2.821, not 3.250. ______ 7. If a null hypothesis is true, then the distribution of the test statistic is known and the p-value measures the likelihood of a test statistic at least as extreme as the one calculated from the data. STATE THE ANSWER. Write the answer on the line. (3 points each) ______________ 8 . What is the P(t > 3.610) if df = 18? ______________ 9. State the value of t o , if the P(t > t o ) = .95 and the df = 26. _____________ 10. What is the P( - 2.821 < t < 2.821) if df = 9?
