You have a falafel cart and you sell falafel every weekday near Washington Square Park during lunch time. Your daily revenue is normally distributed with a mean of $200 and a standard deviation of $50.

(a) Suppose there is another location that might be worth switching to. You plan to experiment with selling there for awhile, and then use a hypothesis test to determine whether you should switch. If the new location has a normally distributed revenue with a true mean of 210 and a standard deviation of 50, how many days would you have to try selling there to have a power of 50%. Use an α = .05 (significance level).

(b) Suppose you try selling at another location for 16 days, and on average you sell $220 worth of falafel with a sample standard deviation of $36 Using an α = .05, test whether the new location is worth switching to.

An amusement park studied methods for decreasing the waiting time (minutes) for rides by loading and unloading riders more efficiently. Two alternative loading/ unloading methods have been proposed. To account for potential differences due to the type of ride and the possible interaction between the method of loading and unloading and the type of ride, a factorial experiment was designed. Use the following data to test for any significant effect due to the loading and unloading method, the type of ride, and interaction. Use α = .05. Use both p-Value and Critical-Value approaches.

1. You’re riding your bike in the bike lane through Golden Gate Park. Suddenly, you drift out of the bike lane and into automobile traffic. Fortunately, you quickly move back into the bike lane and continue toward Ocean Beach. This scenario is a metaphor for homeostasis, where the controlled condition (physiologic variable) is the position of the bike on the road (e.g., inside or outside the bike lane). Identify: (a) The established set point for the controlled condition (b) The receptor (c) The control center (integration center) (d) The effector There’s no need to explain the physiology of vision or muscle contraction. Rather, demonstrate your understanding of feedback systems by mapping the components of a feedback system onto this scenario.

Question UPDATED (3 parts)

Waterways has two major public-park projects to provide with comprehensive irrigation in one of its service locations this month. Job J57 and Job K52 involve 15 acres of landscaped terrain, which will require special-order, sprinkler heads to meet the specifications of the project. Using a job cost system to produce these parts, the following events occurred during December.

Raw materials were requisitioned from the company’s inventory on December 2 for $ 5,064; on December 8 for $ 1,068; and on December 14 for $ 3,450. In each instance, two-thirds (2/3) of these materials were for J57 and the rest for K52.

Six time tickets were turned in for these two projects for a total amount of 18 hours of work. All the workers were paid $ 17.5 per hour. The time tickets were dated December 3, December 9, and December 15. On each of those days, 6 labor hours were spent on these jobs, two-thirds (2/3) for J57 and the rest for K52.

The predetermined overhead rate is based on machine hours. The expected machine hour use for the year is 2,093 hours, and the anticipated overhead costs are $ 837,200 for the year. The machines were used by workers on projects K52 and J57 on December 3, 9, and 15. Six machine hours were used for project K52 (2 each day), and 8.5 machine hours were used for project J57 (2.5 the first day and 3 each of the other days). Both of these special orders were completed on December 15, producing 200 sprinkler heads for J57 and 100 sprinkler heads for K52.

Additional job order activities during this period included:

Part 1

Set up the job cost sheets for Job No. J57 and Job No. K52. Determine the total cost for each manufacturing special order for these jobs. (Round unit costs to 2 decimal places, e.g. 12.25.)

Part 2

Journalize the activities from these job cost sheets in the general journal. Also, journalize the other costs that occurred during this period. (Credit account titles are automatically indented when amount is entered. Do not indent manually. Record journal entries in the order presented in the problem. Round answers to 0 decimal places, e.g. 5,275.)

Part 3

Assuming that Manufacturing Overhead has a debit balance of $ 3,600, determine whether overhead has been under/over applied and make the adjusting entry. (Credit account titles are automatically indented when amount is entered. Do not indent manually.)

Advanced Inheritance Concepts (Exercise 7)

The Cullerton Park District holds a mini-Olympics each summer. Create a class named Participant with fields for a name, age, and street address. Include a constructor that assigns parameter values to each field and a toString() method that returns a String containing all the values. Also include an equals() method that determines two participants are equal if they have the same values in all three fields.

Create an application with two arrays of at least eight participants each—one holds participants in the mini-marathon, and the other holds participants in the diving competition. Prompt the user for participant values. After the data values are entered, display values for participants who are in both events.

(Using R Scholar) For each of the distributions, begin by creating 1000 random samples, each of size ?. Then, for each of the 1000 samples, you will calculate the sample average, ?̅. After calculating 1000 different ?̅’s, you will be able to make a histogram and normal probability plot of the ?̅ values and thus visualize the distribution of ?̅. The goal is to see what value of ? is large enough for the distribution of ?̅ to become approximately normal. Notice that this value of ? depends on the population distribution. To determine the value of ? required, your simulations will start from a small ? and progress to larger ?'s. You will assess the normality based on the plots for each ? and continue until either you have finished the values of ? listed or increased the values until observing sufficient normality in the plots.

For each of the distributions below, you will complete the following: (0.2 points) Code: You only need to provide one code listing for each distribution (i.e. you don’t need to repeat the code for each choice of ?).

2. (0.5 points) Histogram/normal probability plots For each of the values of ?, submit a histogram (with the two colored curves) and a normal probability plot. For each of the graph pairs, indicate whether they appear sufficiently normal or not. No explanation is required. Make sure you increase ? until the distribution of ?̅ appears sufficiently normal.

3. (0.3 points) Summary table This table contains the experimental mean and standard deviation calculated from the data (output is required for each value of ?) and the theoretical mean and standard deviation calculated from Equations 1 (with work for one of the values for each distribution where ? ≠ 1). The format for this table for Part B is below. Make sure you increase ? until the distribution of ?̅ appears sufficiently normal.

A. (1 points) Standard Normal Distribution. ? = 1, 3, 7 and 15.

B. (1 points) Uniform distribution over the interval (0, 8). ? = 1, 3, 7 and 15.

C. (1 points) Gamma distribution with parameters ? = ?. ?? and ? = ?. ? = 1, 5, 10, 20, 40, and continue in intervals of 20 if needed until the shape becomes normal. This distribution has population mean and standard deviation of ? = 1.805, ? = 0.95.

D. (1 points) Poisson distribution with parameter ? = ?. ?. ? = 1, 5, 10, 20, 40, and continue in intervals of 20 if needed until the shape becomes normal.
