9.2.17 Question Help A simple random sample of size nis drawn from a population that is normally distributed. The sample mean, X, is found to be 106, and the sample standard deviations, is found to be 10. (a) Construct a 96% confidence interval about if the sample size, n, is 17 (b) Construct a 96% confidence interval about if the sample size, n, is 22 (c) Construct a 98% confidence interval about if the sample size, n, is 17 id...
(a) Is there a difference in the measurement of the muzzle velocity between device A and device B at the α = 0.01 level of significance? Note: A normal probability plot and boxplot of the data indicate that the differences are approximately normally distributed with no outliers. Let di = Ai − Bi. (i) Identify the null and alternative hypotheses. (ii) Determine the test statistic for this hypothesis test (t0 = ?). Round to two decimal places as needed. (iii)...
(a) Does the evidence suggest that community college transfer students take longer to attain a bachelor's degree? Use an α = 0.05 level of significance. Perform a hypothesis test. Determine the null and alternative hypotheses. (b) Determine the test statistic (t = ?) and the P-value (P = ?). Round to two decimal places as needed. (c) Construct a 90% confidence interval for (μcommunity college − μno transfer) to approximate the mean additional time it takes to complete a bachelor's...
T Distribution Table The U.S. Dairy Industry wants to estimate the mean yearly milk consumption. A sample of 25 people reveals the mean yearly consumption to be 82 gallons with a standard deviation of 24 gallons. Assume that the population distribution is normal. (Use Distribution Table.) a-1. What is the value of the population mean? 82 24 Unknown a-2. What is the best estimate of this value? Estimate population mean c. For a 90% confidence interval, what is the value...
why is thr p value 0.001 if the value falls off of the table and the greatest number is 3.965 so shouldnt jt be .0005? 1. Hutchinson-Gilford progeria syndrome is a rare genetic condition that produces rapid aging in children. In individuals with the syndrome, cardiovascular disease in a common cause of death in the teenage years. A clinical study examined the effect of treatment with the drug lonafarnib and measured the pulse wave velocity (PWV), an important component of...
Full data set Uncarpeted A researcher wanted to determine if carpeted or uncarpeted rooms contain more bacteria. The table shows the results for the number of bacteria per cubic foot for both types of rooms. A normal probability plot and boxplot indicate that the data are approximately normally distributed with no outliers. Do carpeted rooms have more bacteria than uncarpeted rooms at the α 0.01 level of significance? 1 Click the icon to view the Student t-distribution table 13. Carpeted...
I ONLY NEED HELP WITH PART OF PART "B" I've figured out the test statistic is -1.73 and the degrees of freedom are 5. However, I'm having a hard time finding the P value via the chart (which I'm required to learn how to do).I think the chart immediately bellow this is the one used to find the p-value. However, I know at least one (or more) of the charts bellow is what's used. Please let me know which chart...
