Identify/state each: null and alternative hypotheses, inputs/calculation for test statistic, P-value (sketch), decision about null hypothesis, and final conclusion addressing original claim. Test by P-value. a) Show entire test without calculator function. b) Check using calculator function and compare results! 6) The health of employees is monitored by periodically weighing them in. A sample of 54 employees has a mean weight of 183.9 lb. Assuming that o is known to be 98.2 lb, use a 0.10 significance level to test the claim that the population mean of all such employees weights is less than 200 lb.

What is a sample space?

What term is used to express the likelihood of an event occurring? Are there restrictions on its values? If so, what are they? If not, explain.

Tourism is extremely important to the economy of Florida. Hotel occupancy is an often-reported measure of visitor volume and visitor activity (Orlando Sentinel, May , ). Hotel occupancy data for February in two consecutive years are as follows. Current Year    Previous YearOccupied Rooms    1,470    1,360Total Rooms    1,750    1,700Conduct a hypothesis test. What is the -value (to  decimals)? Use Table 1 from Appendix B. p-value = ??  Using a level of significance, what is your conclusion?   d. What is the  95% confidence interval estimate of the change in occupancy for the one-year period (to decimal?   to

Do student IQ scores differ significantly from the population (μ = 100 & σ = 15)? components: state the null and alternative hypotheses (either with words or symbols), report the test statistics along with other important information (df, critical value, descriptive statistics like means and standard deviations, effect size, etc.), and a detailed interpretation of your findings. The interpretation of your results should be written for someone who is unfamiliar with statistics

A data set includes data from 400 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 2.2 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. A 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? О А. Но: и3D2.2 miles H1:µ 2.2 miles Identify the test statistic. (Round to two decimal places as needed.) Identify the P-value. (Round to three decimal places as needed.) State the final conclusion that addresses the original claim. Ho. There is evidence to support the claim that the mean tornado length is greater than 2.2 miles

Researchers conducted a study to assess the effect of an education campaign in increasing knowledge of Treatment as Prevention as a method of preventing transmission of HIV. Each participant's knowledge was assessed before and after a brief education campaign. Knowledge was assessed using a seven-point scale where 1 represents low knowledge and 7 represents high knowledge State the null hypothesis and alternative hypothesis for this study.  b) What test is appropriate to test your null hypothesis? Why is this test appropriate? Provide supporting figures and/or statistics to justify your decision.

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 2.4 miles. Use a 0.05 significance level.
