Tardigrades, or water bears, are a type of micro-animal famous for their resilience. In examining the effects of radiation on organisms, an expert claimed thatthe amount of gamma radiation needed to sterilize a colony of tardigrades no longer has a mean of 1150 Gy (grays). (For comparison, humans cannotwithstand more than 10 Gy.) A random sample of 25 tardigrade colonies found that the amount of gamma radiation needed to sterilize a colony had a samplemean of 1133 Gy, with a sample standard deviation of 62 Gy. Assume that the population of amounts of gamma radiation needed to sterilize a colony oftardigrades is approximately normally distributed.Complete the parts below to perform a hypothesis test to see if there is enough evidence, at the 0.05 level of significance, to support that u, the mean amountof gamma radiation needed to sterilize a colony of tardigrades, is not equal to 1150 Gy.(a) State the null hypothesis H, and the alternative hypothesis H, that you would use for the test.H: 1H: ]O=D0ローロ(b) Perform a hypothesis test.

Q4A The British Department of Transportation studied to see if people avoid driving on Friday the 13th. They did a traffic count on a Friday and then again on a Friday the 13th at the same two locations ("Friday the 13th," 2013). The data for each location on the two different dates is in following table: Table: Traffic Count Dates 6th 13th 1990, July 139246 138548 1990, July 134012 132908 1991, September 137055 136018 1991, September 133732 131843 1991, December 123552 121641 1991, December 121139 118723 1992, March 128293 125532 1992, March 124631 120249 1992, November 124609 122770 1992, November 117584 117263 Let μ1 = mean traffic count on Friday the 6th.

PLEASE ANSWER ALL PARTS OF THE QUESTION AND USE THE IMAGE FOR A GUIDE A biologist is studying the effect of fertilizer on a species of endangered plant in a specific area of land divided into 32 equal sized plots. (See diagram.) Plots numbered 1—16 are in deep shade from the trees for most of the day while periodic flooding occurs in the areas numbered 17—32. The biologist chooses 16 plots at random and applies organic fertilizer. The other plots receive non-organic fertilizer. At the end of the study period, the percentage increase in the number of this plant is measured in each plot and compared for each type of fertilizer. Is this an experiment? Briefly explain your answer. A biologist is studying the effect of fertilizer on a species of endangered plant in a specific area of land divided into 32 equal sized plots. (See diagram.)

High-Speed Train Company The tourism director for a hlgh-speed train company was Interested in flnding out the precise time the train passed by some special landmarks. To help her figure this out, she began by collecting some data for the Palmetto traln that originates from New York City Penn Station and ends at Richmond, VA, stopping at varlous locations along the route. Palmetto - Time Distance from Train #89 cumulative NY Daily (minutes) (miles) Location of Train Stops New York, NY - Penn Station 6:15AM Newark, NJ 6:32AM 17 13 Trenton, NJ 7:06AM 51 66 7:37AM 82 96 Philadephia, PA Wilmington, DE 8:02AM 107 125 Baltimore, MD 8:54AM 159 190 Washington Dc 9:55AM 220 227 Alexandria, VA 10:12AM 237 238 Richmond, VA - Staples Mill Road 11:50AM 335 335 1.

The time it takes an employee to package the components of a certain product is normally distributed with ? = 7.5 and ? = 1.5 minutes. As an incentive, management has decided to give a bonus to the 25% of employees who took the shortest amount of time to package the components. Find the amount of time taken to package the components that will indicate that an employee should get a bonus. (Round your answer to two decimal places.) An employee must package components in a time minutes.

Q2 Fifteen adults of males between age of 35 and 50 participated in a study to evaluate the effect of diet and exercise on blood cholesterol level. The total cholesterol was measure in each subject initially and then three month after participating in aerobic exercise program and switching to low fight diet. The data are shown in the table below: Before 256 240 258 295 251 205 238 247 225 294 238 229 After 229 231 227 234 218 218 230 243 221 240 219 211 a. Do the data support the claim that low fat diet and aerobic exercises are of value in producing a mean reduction in blood cholesterol level at 5 % level of significance? (show all steps of hypothesis testing) b. Construct a one sided confidence interval that can be used to answer the question in part a. Check the results obtained in part a using R-Studio. Write your conclusion based on the p-value obtained in R studio. C.
