One hundred teachers attended a seminar on mathematical problem solving. The attitudes of representative sample of 12 of the teachers were measured before and after the seminar. A positive number for change in attitude indicates that a teacher's attitude toward math became more positive. The twelve change scores are as follows. 4; 8; −1; 1; 0; 4; −3; 2; −1; 5; 4; −2
B) What is the standard deviation for this sample? (Round your answer to two decimal places.)
C) What is the median change score? (Round your answer to one decimal place.)
D) Find the change score that is 2.2 standard deviations below the mean. (Round your answer to one decimal place.)

Task: Apply mathematical problem solving skills to a
variety of problems at the college level.
To accomplish this task, the students will
1. Identify what they are given and what they need to find;
2. Identify the type of problem they have been given and the
tools necessary to solve the problem;
3. Correctly apply the tools to the information given to set up
the problem;
4. Perform mathematically correct calculations to determine a
solution;
5. Interpret their results in...

A researcher wanted to know whether losing one night sleep can
affect problem solving. A sample of n = 25 college
students was given a problem-solving task at noon on one day and
again at noon on the following day. The students were not permitted
any sleep between the two tests. For each student, the difference
between the first and the second score was recorded:
MD = 4.7 and standard deviation of the
difference score was s = 8.

Problem: Certain mathematical problems involve
manipulation of the digits within a whole number. One such problem
requires that the digits be re-arranged.In this project, we will
reverse the order of the digits in a number.
Assignment: Design, develop, and test an
Object-Oriented C++program that reads a whole
number from the user, removes the sign and all leading and trailing
zeroes from that number, and then performs the following operations
on that number: 1) reverses the digits, 2) sorts the digits...

Summarize the strategic hands for problem-solving, and give an
example of the meaning of each one
which of the following best summarizes the strategic hand there may
be more than one strategy and provide an example of the meaning
A there may be several strategies to solving the problem,
however only one of them will find the correct answer. For example,
there is more than one strategy to stop exit squared plus 3X +2 = 0
however, only one of...
