A sample sequence of 35 products is selected (in order) from an assembly line. Each product is examined and judged to be either acceptable or defective. A total of 26 of these products were found to be acceptable, and the other 9 were found to be defective. The number of runs was 7. The runs test is to be used at the 0.05 significance level to test for randomness. Find the value of the test statistic used in this test, and round it to 3 places after the decimal point (if necessary)

Two snooker players, Player A and Player B, play a match of a ‘best-of-seven’ frames of snooker, i.e. the first player to win 4 frames wins the match. The probability Player A wins a frame is 0.55 and the probability Player B wins a frame is therefore 0.45.
(a) What is the probability that Player A wins the match by a score
of 4-2?
(b) What is the overall probability Player B wins the match?
(c) What is the expected number of frames played in a match?

Java - Create a program that simulates a slot machine. When the program runs, it should do the following: - Ask the user to enter the amount of money he or she wants to enter into the slot machine. - Instead of displaying images, have the program randomly select a word from the following list: Cherries, Oranges, Plums, Bells, Melons, Bars (To select a word, the program can generate a random number in the range of 0 through 5. If the number is 0, the selected word is Cherries, if the number is 1, the selected word is Oranges, and so forth. The program should randomly select a word from the list three times and display all three of the words.) - If none of the randomly selected words match, the program informs the user that he or she has won $0. If two of the words match, the program informs the user that he or she has won two times the amount entered. If three of the words match, the program informs the user that he or she has won three times the amount entered. - The program asks if the user wants to play again. If so, these steps are repeated. If not, the program displays the total amount of money entered into the slot machine and the total amount won.
If you could just take a screen shot of the actual code on java that would be great. A lot of the characters appear differently when answer is copied and pasted on answer forum.

Write a method, twoSumSorted2, that solves the following variant of the Two-Sum problem:
Given a sorted array of integers where each element is unique and a target integer, return in an Array List, the indices of all pairs of elements that sum up to the target. Each pair of indices is also represented as an Array List (of two elements). Therefore, the method returns an Array List of an Array List of size 2. If no pair in the input array sums up to the target, then the method should return an empty list.
public class Hw2_p1 {
// HW2 Problem 1 Graded Method
public static
ArrayList<ArrayList<Integer>> twoSumSorted(int[] A, int
target) {
ArrayList<ArrayList<Integer>> ans = new
ArrayList<>();
// Your code starts
// Your code ends
return ans;
}
// Test driver for twoSumSorted2
public static void main(String[] args) {
}
}
The following are two sample runs:
Input: ? = [−7, −5, −2, 0, 1, 6, 7, 8, 9], ?????? = 1
Return value: [0,7], [1, 5], [3, 4]
Explanation: The pairs in the input array that sum up to 1 are [−7, 8], [−5, 6] and [0, 1]. Their indices are [0, 7], [1, 5] and [3, 4] respectively.
Input: ? = [−2, 0, 1, 6, 7, 8], ?????? = 3
Return value: [ ]
Explanation: No pair of elements in input array sums up to 3. The returned list is thus empty.
Your method must have time complexity ?(?), where ? is the length of the input array.

The Gourmand Cooking School runs short cooking courses at its small campus. Management has identified two cost drivers it uses in its budgeting and performance reports—the number of courses and the total number of students. For example, the school might run two courses in a month and have a total of 50 students enrolled in those two courses. Data concerning the company’s cost formulas appear below: Fixed Cost per Month Cost per Course Cost per Student Instructor wages $ 3,080 Classroom supplies $ 260 Utilities $ 870 $ 130 Campus rent $ 4,200 Insurance $ 1,890 Administrative expenses $ 3,270 $ 15 $ 4 For example, administrative expenses should be $3,270 per month plus $15 per course plus $4 per student. The company’s sales should average $800 per student. The company planned to run three courses with a total of 45 students; however, it actually ran three courses with a total of only 42 students. The actual operating results for September appear below: Actual Revenue $ 32,400 Instructor wages $ 9,080 Classroom supplies $ 8,540 Utilities $ 1,530 Campus rent $ 4,200 Insurance $ 1,890 Administrative expenses $ 3,790 Required: 1. Prepare the company’s planning budget for September. 2. Prepare the company’s flexible budget for September. 3. Calculate the revenue and spending variances for September.

In an effort to characterize the New Guinea crocodile (Crocodylus novaeguineae), measurements were taken of the dorsal cranial length (mm) (the length of the skull from the tip of the nose to the back of the cranial cap, denoted DCL) and the total length (cm) (denoted TL) of 50 harvested adult males.
A: DCL > 260mm, B: TL > 180cm.

A protein solution was placed in an analytic centrifuge and spun
until equilibrium was reached. The measurement was then repeated.
But it was realized, too late, that prior
to the second run, the protein had been denatured. The average size
of a denatured protein is larger than that of a native, compact
protein. (a) Do you expect the distribution of molecules to be the
same, at equilibrium, for the two different runs? Explain. (b) The
time that it takes to reach equilibrium depends on the
sedimentation constant of the molecules. Which run will reach
equilibrium faster, the one with the native protein, or the one
with the denatured protein? Explain how you imagine the
sedimentation process of the two molecules.

A school is interested in whether its student's scores on a
standardized test exceed the
national average. The national average is 40 (μ = 40) and the
standard deviation is 8 (cr =
8). To determine this, the school officials administer the test to
a sample of 16 (n = 16)
students and obtain a mean score of 44 (M = 44). Perform a z-test
to determine whether
the students in the school differ significantly from the
national average. Perform a two-
tailed test. Compute the obtained z score.
