The health of employees is monitored by periodically weighing them. Asample of 54 employees has a mean weight of 184.1 lb. Assuming that thepopulation standard deviation is 122.3 lb, use a 0.10 significance level to test theclaim that the mean of all such employees weights is less than 200 lbs.
The mean waiting time for non-emergency surgeries in your hospital is 87.5 days with astandard deviation of 14 days. Over the last year the hospital’s CEO has beenimplementing various programs to try to reduce the waiting time. You are asked to testwhether the wait times have changed from the previous average. Not knowing if thewait times have increased or decreased, you hypothesize that the wait times are not 87.5days. You randomly select 100 cases and calculate the average wait time, which is 84days. Use ?= 0.05
According to a study, a cup of coffee contains an average of 118 milligrams (mg) of caffeine, with the amount poer cup ranging from 56 to 187 mg. Suppose you want to repeat the experiment in prder to obtain an estimate of the mean caffeine content in a cup of coffee correct to within 7 mg with 99% confidence. How many cups of coffee would have to be included in your sample? The experiment must sample cups of coffee in order to estimate the mean caffeine content in a cup of coffee correct to within 7 mg with 99% confidence. Round up to the nearest whole number.)

According to the Bureau of Crime Statistics and Research of Australia as reported on Lawlink, the mean length of imprisonment for motor vehicle theft offenders in Australia is 16.7 months. Thirty randomly selected motor vehicle theft offenders in Sydney Australia had mean length of imprisonment of 17.8 months. The population standard deviation of the lengths of imprisonment for motor vehicle theft offenders in Sydney is 6.0 months. At 5% significance level, do the data provide sufficient evidence to conclude the mean value of imprisonment for motor vehicle theft offenders in Sydney differs from the national mean in Australia? Construct 99% confidence interval of the lengths of imprisonment for motor vehicle theft offenders in Sydney for true mean.
DO NOT USE MICROSOFT EXCEL. Provide a step-by-step solution with NORMAL CURVE. Please write legibly. Test the hypothesis that a coffee-vending machine spills an average of 240 milliliters of coffee in a single operation. Ten cups of coffee are examined and are found to contain 245, 238, 246, 242, 237, 241, 236, 238, 240, and 241 milliliters of coffee, respectively. Use a 0.05 level of significance and assume that the distribution of contents is normal.
A data set includes data from 500 random tornadoes. The display from technology available below results from using the tornado lengths (miles) to test the claim that the mean tornado length is greater than 2.5 miles. Use a 0.05 significance level. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. Click the icon to view the display from technology. Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses? O A. Ho: µ=2.5 miles O B. Ho: H= 2.5 miles H,: µ#2.5 miles H,: µ> 2.5 miles Ο C. H : μ < 25 miles O D. Ho: µ=2.5 miles H;: µ<2.5 miles H,: µ=2.5 miles
Identify the test statistic. Identify the P-value. State the final conclusion that addresses the original claim.
