Suppose query Q1 obtains the median ml of a set S1 of values, and query Q2 obtains the median m2 of a subset S2 of S1. If m1 < m2, what can be inferred about S1, S2, and the elements of S1 not in S2?
Let suppose S1 be the number of MALE employees,S2 be the number of employees(both genders) got salary hike.
S1 not in S2 means the employees that does not got salary hike,
if M1<M2 ,then a lower proportion of males than females got salary hike.
If i say that S1 be the number of MALE employees,S2 be the number of employees(both genders) got salary hike.
S1 not in S2 means the employees that does not got salary hike,
if M1<M2 ,then a lower proportion of males than females got salary hike.

Produce a method that reads in a set of values (double) from the
user and returns them. Use this header:
public static double[] getNumsFromUser(String msg1,
String msg2)
The implementation of the method should start with a message to
input the total number of array elements, followed by a message to
enter all the array elements. The method returns the array of
elements. The two strings msg1 and msg2 that are passed to the
method as parameters will be...

1. Consider the alphabet set Σ = (0,1,2) and the enumeration ordering on Σ*, what are the 20th and 25th elements in this ordering? 2. Let N be the set of all natural numbers. Let S1 = { Ag N is infinite }, S2-( A N I A is finite) and S-S1 x S2 For (A1,B1) E S and (A2,B2) E S, define a relation R such that (A1,B1) R (A2,B2) iff A1CA2 and B2CB1. i) Is R a...
6. The median, or Q2, is nothing special. When creating a sign test, we could have designed the testing infrastructure around the first quartile, Q1, instead. Suppose we set a null hypothesis of Ho: q = go, where q is a symbol for the first quartile, go is a constant, and we are dealing with a continuous random variable X. a. Assuming Ho, we collect n values from X: Xi,..., Xn If U is the number of observations less than...

Use the following for Q1 and Q2. Suppose in a class of 140 students 35 of them are Biology Majors. Q1 Q1. ( point) If a student is chosen at random what is the likelihood they will be a Biology Major? P(Biology Major) Q2. (1 point) If a student is chosen at random what is the likelihood they are not a Biology Major? P(Not Biology Major) Use the following for Q3 and Q5. Suppose at an ice cream shop there...
Suppose two firms compete by selecting quantities q1 and q2, respectively, with the market price given by p = 1000-3q1 -3q2. Firm 1 (the incumbent) is already in the market. Firm 2 (the potential entrant) must decide whether or not to enter and, if she enters, how much to produce. First the incumbent commits to its production level q2. The potential entrant, having seen q1, decides whether to enter the industry. If firm 2 chooses to enter, then it selects...
Three charges are located as shown in the figure, with values q1=4.9 x 10-16 C, q2=-1.7 x 10-16 C, q3=6.5 x 10-16 C. The charges are separated by d1=3.6x 10-6 m and d2=2.7x 10-6m. Part (a) What is the force of q2 on q1 in the x direction, Fx? Give your answer in newtons, and recall k = 8.988 x 109 N m2/C2 Part (b) What is the force of q3 on q1 in the y direction, Fy? Give your answer in...
