The following data is based on information taken from Winter Wind Studies in Rocky Mountain National Park by D. E. Glidden (Rocky Mountain Nature Association). At five weather stations on Trail Ridge Road in Rocky Mountain National Park, the peak wind gusts (in miles per hour) for January and April are recorded below:
| Weather station | 1 | 2 | 3 | 4 | 5 |
| January | 139 | 122 | 126 | 64 | 78 |
| April | 104 | 112 | 100 | 88 | 61 |
Does this information indicate that peak wind gusts are higher in January than in April? Use a .03 significance level. Please use the four step process and round your answers to the nearest fourth decimal place.

Henderson is on a business trip in New Jersey. He drove his car from New York to New Jersey and checks into the Hotel Ritz. The Ritz has a guarded underground parking lot. Henderson gives his keys to the parking attendant, but did not tell him that his wife’s expensive ($15,000) fur coat was in the car. The coat was packed in a box in the trunk of the car. When Henderson went to check out the next day, he realized his car had been stolen. Henderson is very upset and wants to hold the hotel liable for the car and his wife’s $15,000 fur coat.
what will the insurance company do? Will they acknowledge the claim since the car was stolen at no fault to the owner? How will the owner prove that the coat was lost?

You are working on a bid to build two city parks a year for the next three years. This project requires the purchase of $210,000 of equipment that will be depreciated using straight-line depreciation to a zero book value over the 3-year project life. The equipment can be sold at the end of the project for $34,000. You will also need $21,000 in net working capital for the duration of the project; all net working capital will be recovered at the end of the project. The fixed costs will be $19,000 a year and the variable costs will be $150,000 per park. Your required rate of return is 12 percent and your tax rate is 34 percent. What is the minimal amount you should bid per park? (Round your answer to the nearest $100)

Let x be a random variable that represents the weights in kilograms (kg) of healthy adult female deer (does) in December in a national park. Then x has a distribution that is approximately normal with mean μ = 54.0 kg and standard deviation σ = 8.5 kg. Suppose a doe that weighs less than 45 kg is considered undernourished. (a) What is the probability that a single doe captured (weighed and released) at random in December is undernourished? (Round your answer to four decimal places.) (b) If the park has about 2400 does, what number do you expect to be undernourished in December? (Round your answer to the nearest whole number.) does (c) To estimate the health of the December doe population, park rangers use the rule that the average weight of n = 70 does should be more than 51 kg. If the average weight is less than 51 kg, it is thought that the entire population of does might be undernourished. What is the probability that the average weight x for a random sample of 70 does is less than 51 kg (assuming a healthy population)? (Round your answer to four decimal places.) (d) Compute the probability that x < 56 kg for 70 does (assume a healthy population). (Round your answer to four decimal places.) Suppose park rangers captured, weighed, and released 70 does in December, and the average weight was x = 56 kg. Do you think the doe population is undernourished or not? Explain. Since the sample average is below the mean, it is quite likely that the doe population is undernourished. Since the sample average is above the mean, it is quite unlikely that the doe population is undernourished. Since the sample average is above the mean, it is quite likely that the doe population is undernourished. Since the sample average is below the mean, it is quite unlikely that the doe population is undernourished.

I am supposed to answer these conceptual questions with this lab simulator, but I can never get the simulator to work https://phet.colorado.edu/en/simulation/legacy/energy-skate-park
Help please?
Energy State Park Lab Handout
Click on the “Energy State Park Simulation” link to perform simulations in the setup satisfying the given conditions.
Upon opening the simulation, the skate should be alternating between the walls of the skate park with no friction added and with Earth’s gravity. Click on the Show Pie Chart under the Energy Graphs section.
Now change the coefficient of friction to half way between None and Lots.
