Q 15 Question 15 Consider the following sample of 11 length-of-stay values (measured in days): 1, 1, 3, 3, 3, 4, 4, 4, 4, 5, 7 Now suppose that due to new technology you are able to reduce the length of stay at your hospital to a fraction 0.5 of the original values. Thus, your new sample is given by .5, .5, 1.5, 1.5, 1.5, 2, 2, 2, 2, 2.5, 3.5 Given that the standard error in the original sample was 0.5, in the new sample the standard error of the mean is _._.

Question #1 (16 points)

A consumer group was interested in comparing the performance of three models of cars. Random samples of six owners were drawn from a list of each model. The owners were asked how many times their cars had undergone repairs in the past 2 years. Using alpha =.01, follow the 8 steps to hypothesis testing to determine whether the cars different significantly in terms of repairs needed.

The mere presence of oversized arrays makes Priscilla Perfect sick to her stomach. Such wasted space is an imperfection she cannot bear. As her oldest and dearest friend this worries you greatly. If you were a doctor you might try to find a cure to her sickness, but you are a programmer. A program must be written to alleviate her pain!

For any array given that has empty slots create a new array that is perfect. Unused slots will have a value of 0. All unused slots are guaranteed to be at the end of the array. There will never be unused slots in the middle.
java.util.Arrays has been enabled.

Examples:

makePerfect({1, 1, 4, 5, 6, 0, 0, 0, 0}) -> {1, 1, 4, 5, 6}

makePerfect({1, 3, 4, 2, 6, 0, 0, 0, 0}) -> {1, 3, 4, 2, 6}

R programming language

A) Create a function that accepts two arguments, an integer and a vector of integers. It returns the count of the number of occurrences of the integer in the input vector.

1]Input: num_count <-function ???

2]Input: num_count(2,c(1,1,2,2,3,3))

2] Output: 2

3] Input: num_count(1,c(1,1,2,2,3,1,4,5,5,2,2,1,3))

3] Output : 4

B) Create a function that accepts 3 integer values and returns their sum. However, if an integer value is evenly divisible by 3, then it does not count towards the sum. Return zero if all numbers are evenly divisible by 3. Hint: You may want to use the append() function.

1] Input: summer <- function???

2] Input: summer(7,2,3)

2] Output: 9

3] Input: summer(3,6,9)

3] Output:0

4] Input: summer(9,11,12)

4] Output: 11

C)Create a function that will return TRUE if an input integer is prime. Otherwise, return FALSE. You may want to look into the any() function

1]Input: prime_check <- function ???

2]Input: prime_check(2)

2]Output:  TRUE

3] Input: prime_check(5)

3] Output: TRUE

4] Input: prime_check(4)

4] Output: FALSE

5]Input: prime_check (237)

5] Output: FALSE

6] Input: prime_check(131)

6] Output: TRUE

Write a C++ program to run a menu driven program with the following choices:

1) Display the grades
2) Adjust grade
3) Display Average for each student
4) Display number of student with at least a B

5) Quit

requirements:

1. Write a function called getValidGrade that allows a user to enter in an integer and loops until a valid number that is >= 0 and <= 100 is entered. It returns the valid value.

2. Write a function called getValidStudentNumber that allows a user to enter in an integer and loops until a valid number that is >= 0 and < NUM_STUDENTS is entered. It returns the valid value.

3. Write a function called getValidAssignmentNumber that allows a user to enter in an integer and loops until a valid number that is >= 0 and < NUM_GRADES is entered. It returns the valid value.

4. Write a function called displayGrades that takes the student and grade arrays as parameters and displays the grades in the format in the sample run below.

5. Write a function called displayAverageForEachStudent that takes the student and grade arrays as parameters, computes the average grade for each student, and displays the grades in the format in the sample run below.

6. Write a function called displayNumStudentsAtLeastBForSelectedAssignment that takes the student and grade arrays as parameters, allows the user to select a valid assignment and locates and displays the number of the student with at least a grade >= 80 for that assignment in the format in the sample run below.

7. Write a function called AdjustGrade that takes grade arrays as a pass by reference parameter, allows the user to select a valid student, a valid assignment, and a valid grade and changes the student assignment grade to the value entered.

8. Add comments wherever necessary.
