The FBI wants to determine the effectiveness of their 10 Most Wanted list. To do so, they need to find out the fraction of people who appear on the list that are actually caught.

Suppose a sample of 879 suspected criminals is drawn. Of these people, 677 were not captured. Using the data, construct the 95% confidence interval for the population proportion of people who are captured after appearing on the 10 Most Wanted list. Round your answers to three decimal places. Answer

Consider the set of five numbers {0, 2, 4, 6, 8}.

1) Make a list of all possible samples of size 2 that can be drawn from this set of integers. (Sample without replacements, that is, once a number is selected, you don’t put it back in the sample set.)

2) Make a list of all possible sample means for samples of size 2 selected from this set.

3) List the distribution of the sample means and construct a histogram of this distribution.

I flip a fair coin and recorded the result. If it is head, I then roll a 6-sided die: otherwise, I roll a 4-sided die and record the results. Let event A be the die has a 3 or greater. let event B be I flip tails. (a)-List all the outcomes in the Sample space (b)- List the outcomes in Event A and B (c)- List the outcomes in A or not B (d)- Calculate the probability of event A (e) Calculate the probability of A and not B.

Function named FunCount takes three arguments-

C, an integer representing the count of elements in input list

IP- input list of positive integers.

Item- an integer value.

Function FunCount returns an integer representing the count of all the elements of List that are equal to
the given integer value Key.

Example: Don’t take these values in program, take all inputs from user

C = 9, IP= [1,1,4,2,2,3,4,1,2], Item = 2
function will return 3

1. What is output by the following C++ code segment? Assume myList is an initially empty linked list that can store floats. Draw the linked list (with head, nodes, and pointers) to show how it looks conceptually by the time the code completes executing.

FloatList myList;

myList.insertNode(5.25);

myList.insertNode(2.14);

myList.appendNode(9.11);

for (int x = 1; x < 4; x++)

   myList.insertNode(x * 0.1);

myList.deleteNode(2.14);

myList.displayList();

Output:

Linked list drawing:

I read a claim that 40% of Americans struggle to afford at least one basic need for housing, healthcare, utilities, or food. A Math 146 student hopes this proportion is lower for Bellingham Technical College students.

Part A) what are null and alternate hypotheses?

Part B) the student conducts a random survey of 56 fellow students at BTC which returns a sample proportion of 38% who cannon afford basic needs. Test the claim 5% significance leve. State all reasoning, steps, values and interpretations needed for the test.

Part C) Should we accept or reject the null hypotheses? state the conclusion of this study with respect to the claim in clear simple language.

Prompt: Suppose you are trying to show that there is a relationship between gender, living arrangement and the number of texts sent daily among students. You take a sample of 12 students, record their gender (F&M) and ask whether they live at home (H), campus (C), or off campus (O)

Questions: (Known top row effect = +3, sum of square total =244)

1. What is the sum of squares interaction? (correct answer is 32)

2. What is the mean square for the row variable? (correct answer is 108)

Find the linear regression equation (line of best fit), determine the correlation, and then make a prediction.

1. The table below gives the amount of time students in a class studied for a test and their test scores.

Graph the data on a scatter plot, find the line of best fit, and write the equation for the line you draw.

Linear Regression Equation: ____________________

Correlation Coefficient (r): _________

Type of Correlation: ______________________

Is the correlation strong? Explain

Using the linear regression equation predict

a students test score if they studied for 4 hours.

A researcher is interested in the breakfast and exercise habits of college students. For some randomly selected students, he recorded the number of times they had breakfast in one month and the number of times they went to gym. The correlation for these two variables ended up being 0.74. If a college student who had never previously gone to the gym began going to the gym regularly, what does this imply about the future habits of that student?

Select one:

a. He will have breakfast more regularly.

b. He will stop having a breakfast.

c. We cannot conclude that working out in the gym will affect the future breakfast habits of this person.

d. He will have breakfast in the gym.
