Wildhorse Company has provided information on intangible assets as follows.

● Wildhorse incurred research and development costs in 2017 as follows.

Wildhorse estimates that these costs will be recouped by December 31, 2020. The materials and equipment purchased have no alternative uses.

● A patent was purchased from Sandhill Company for $810,000 on January 1, 2016. Wildhorse estimated the remaining useful life of the patent to be 10 years. The patent was carried in Sandhill’s accounting records at a net book value of $1,790,000 when Sandhill sold it to Wildhorse.

● During 2017, a franchise was purchased from Clinton Company for $371,000. In addition, 5% of revenue from the franchise must be paid to Clinton. Revenue from the franchise for 2017 was $1,240,000. Wildhorse estimates the useful life of the franchise to be 10 years and takes a full year’s amortization in the year of purchase.

● On January 1, 2017, because of recent events in the field, Wildhorse estimates that the remaining life of the patent purchased on January 1, 2016, is only 5 years from January 1, 2017.

Prepare a schedule showing the intangibles section of Wildhorse’s balance sheet at December 31, 2017. (Enter account name only and do not provide descriptive information.)

The reaction of nitric oxide, NO, with hydrogen, H₂, produces nitrogen, N₂, and water, H₂O, according to the equation

2 NO + 2 H₂ ? N₂ + 2 H₂O

A student obtained the following data:

(a) Determine the most probable rate equation for the reaction, with v for the reaction rate and k for the rate coefficient.

(b) Evaluate the numerical value (with units) of the rate coefficient.

(c) Choose the appropriate matches below. Note that some of the units have to be expressed in a particular way in the drop down menus, e.g. L⁴ shows as L4, s^-1 looks like s-1, L⁴ s^-1 looks like L4 s-1.

Observation: Hiking trails with more human foot traffic have less woody vegetation (e.g, trees) than hiking trails with less human traffic.

experiment:

• Three trails were assessed during this experiment: one where the foot traffic was measured to be 75-100 pedestrians passing by each hour, the second with only 25-50 pedestrians each hour, and one where there was only 1-10 pedestrians per hour.
• 10 x 10 foot quadrants were laid out at ten locations throughout the trail and the number of woody plants was counted and averaged.

Write a complete methods section describing your experiment design. This methods section should follow all the rules discussed in ecology lab.

7. Suppose that we are given that there exists a random variable X whose distribution is binomial with parameters are n = 500 and p= 0.300, and here X represents the number of desired outcomes of the random experiment and n-X is the number of undesired outcomes obtained from a random experiment of n independent trials. From this random experiment   p̂ sample proportion is found as X/n. (Round your answers to 3 decimal places in all parts.)

1. What is the expected value of this statistic?

Expected value:

2. Within what limits will 99% of the sample proportion occur?

Value of sample proportion is between …................ and …................

3. What is the probability that sample proportion exceed 0.353

Probability:

4. What is the probability that sample proportion less than 0.247

Probability:

3. As we have seen in class, hypothesis testing and confidence intervals are the most common inferential tools used in statistics. Imagine that you have been tasked with designing an experiment to determine reliably if a patient should be diagnosed with diabetes based on their blood test results. Create a short outline of your experiment, including all of the following:

1. A detailed discussion of your experimental design.
2. How is randomization used in your sampling or assignment strategy?
3. The type of inferential test utilized in your experiment.
4. A formal statement of the null and alternative hypothesis for your test.
5. A confidence interval for estimating the parameter in your test.
6. An interpretation of your p-value and confidence interval, including what they mean in context of your experimental design
