/*      Problem 2
*       Suppose there are 4 candidates in 6 districts running for an election.
    Let's assume the candidates' names are: Jane, Amani, Doe, and Macbeth.
        Your task is to print out: 1) the total votes per candidate, and 2) the
        total votes per district.
        
        Here are some hints:
        1) Create a two-dimensional array of type int and name it ballots.
         int [][] ballots = { }. Fill it with votes. Remember, you are going to have
         four columns and six rows.
         
        2) Create the candidates as follows: String [] candidates = { } and
        assign them names.
        
        3) Create an object reference to hold the tally for the votes.
        
        4) Use a for loop to print the totals for candidates. 
        
        5) Use a for loop to print the totals for districts.
        
        Your output should look like:
        Total votes per candidate

Ratio of Cash to Monthly Cash Expenses

Kips Bay Medical Inc. is a medical device company that develops, produces, and sells products used in coronary surgery. The following data (in thousands) were adapted from recent financial statements.

*Includes various short-term securities that are readily convertible to cash.

1. Compute the monthly cash expenses for Years 1 -4. Round your answers to the nearest thousand.

2. Compute the ratio of cash to monthly cash expenses for Years 1 -4. Round your answers to one decimal place.

3. Including short-term investments as part of cash and cash equivalents, compute the ratio of cash to monthly cash expenses for Years 1 -4. Round your answers to one decimal place.

4. Based on the calculations above , which of the following statements is incorrect?

Kips Bay Medical has reported losses and negative cash flows from operations in each of the four years.

Kips Bay Medical was not able to raise funds by issuing stock in Years 1 and 2.

Kips could continue to operate only 7.5 months using cash and 8.6 months using cash and short-term investments.

Long term, Kips Bay Medical must generate positive cash flows from operations in order to remain in business.

Choose the correct answer:
1

5. Based upon the preceding results in (2) and (3), an investment in Kips Bay Medical common stock would be extremely risky . Unless management of Kips could convince you that a turn around was likely and that Kips would generate positive cash flows from operations and profit in the future, you should probably not invest in Kips common stock.

Feedback

1. Keep in mind that monthly cash expense is equal to net cash flows from operations divided by 12.

2. Recall that cash and cash equivalents are divided by monthly cash expenses to arrive at the ratio of cash to monthly cash expenses.

3. Keep in mind that short term investments are added to cash and cash equivalents; then, the total is divided by monthly cash expenses to arrive at the ratio of cash to monthly cash expenses.

4. Keep in mind that short term investments are added to cash and cash equivalents; then, the total is divided by monthly cash expenses to arrive at the ratio of cash to monthly cash expenses.

5. Focus on the negative cash flows generated and losses reported by Kips Bay Medical. Unless the management of Kips convinces investors about future positive cash flows, it is risky to invest in Kips’ common stock.

Snapchat is interested in targeting a particular audience group with a new product(Spectacles)and needs to know about the average time a first-year college student spends on Snapchateach day. This way, they can decide whether or not it would be worthwhile to advertise Spectacles to students. Unfortunately, the Snapchatreport does not include specific information about first-year college students, so they don't have u for this population. They hire Serena to find more information.
She does some research online and finds that Website A claims that first-year college students spend on average 4 hours on Snapchatper day and Website B claims that first-year college students spend on average 3 hours on Snapchatper day. Since both sites made different claims, Serena decides to survey first-year students at De Anza to create a confidence interval to decide if the claims are reasonable. The following is a list of 30 responses (in hours):

1. Input the 30 observations into the list 1L of your calculator and use 1-Var-Stats to determine the sample mean X and the sample standard deviation .sRound your answers to 4 decimal places. Again, assume X is approximately normal.
X=_____________ s= ________________
2. Explain in one sentence why the t distribution must be used to create a confidence interval in this situation.
3. Using the information from problems 2 and 3, construct a 95% confidence interval for the population mean the number of hours spent on Snapchatby first-year college students. Round your answer to 4 decimal places. Show all of your work and interpret the confidence interval.
4. Are the claims made by Website A and Website B reasonable or unreasonable? Make your decision based on your 95% confidence interval from problem 4 and explain.
A. Website A’s claim of u=4 hours is reasonable/unreasonable(circle one) because...
B. Website B’s claim of u=3 hours is reasonable/unreasonable(circle one) because...

A researcher interviews 50 employees of a large manufacturer and collects data on each worker’s hourly wage (Wage), years of higher education (EDUC), experience (EXPER), and age (AGE). The data is shown below; the data set can also be found on the text website; labeled Hourly Wage.

Please use either Minitab or Excel to develop both the scatter plots and find the correlation coefficients.

A. Which variable is the response variable? Which variables are the explanatory variables?

B. Develop a scatter plot comparing wage to education. Interpret the plot.

C. Develop a scatter plot comparing wage to experience. Interpret the plot.

D. Compute the correlation coefficients for wage and education and wage and experience. Then perform a hypothesis test for both correlations to determine if the correlations are statistically significant. Be sure to show the null and alternative hypotheses, decision rule, decisions and conclusions. Use alpha = .05. Note: Since the hypotheses and decision rule are the same for both tests, only need to write those steps once.  

E. Which of the explanatory variables provides the best predictor of the response variable? Support your response by citing both the scatter plot and correlation test.

Write a c program arrays2.c that checks if an integer array contains three identical consecutive elements. Assume the number of identical consecutive elements are no more than three if they exist.
Sample input/output #1:
Enter the length of the array: 11
Enter the elements of the array: -12 0 4 2 2 2 36 7 7 7 43
Output: The array contains 2 of three identical consecutive elements: 2 7
Sample input/output #2:
Enter the length of the array: 4
Enter the elements of the array: -12 0 4 36
Output: The array does NOT contain identical consecutive elements
Sample input/output #3:
Enter the length of the array: 11
Enter the elements of the array: -12 0 4 2 2 2 36 7 7 43 43
Output: The array contains 1 of identical consecutive elements: 2
1) Name your program arrays2.c
2) Include and implement the following function in the program. Do not modify the function prototype.
void search_three(int *a1, int *a2, int n, int *num_three);
The function takes two integer array parameter a1 and a2 of size n. a1 is the input array. a2 is the output array containing the integers that are in the three consecutive integers. num_three as a pointer variable, pointing to the variable for the total number of the three consecutive integers (also the actual size of the output array). For example, the total number of the three consecutive integers for sample input #1 is 2, 0 for sample input #2, and 1 for sample input #3.
The function should use pointer arithmetic – not subscripting – to visit array elements. In other words, eliminate the loop index variables and all use of the [] operator in the function.
3) In the main function, ask the user to enter the size of the input array, declare the input array and output array of the same size, and then ask the user to enter the elements of the input array. The main function calls search_three function, and displays the result.
