Probability and Statistics Problems

Problem 1: Selecting a Group

Florida State University (FSU) wants to select 3 men and 2 women from a group of 8 men and 5 women. How many ways can the group of five persons be selected?

Solution:

  • Ways to select 3 men from 8: 8! / (3! * (8-3)!) = 56
  • Ways to select 2 women from 5: 5! / (2! * (5-2)!) = 10
  • Total ways to select the group: 56 * 10 = 560

Therefore, there are 560 ways to select the group.

Drawing Conclusions and Ascertaining the Importance of Economic Management

Draw conclusions and ascertain the importance of economic management, depending on whether individuals are employed (yes/no).

Conclusions (indicating value means)

  • Importance of “1”: The second chart shows a degree of proof for Levene’s test for equal variances of 0.654 > 0.05. Therefore, Ho is accepted. So, the means (bilateral) for the T-test equal smear result medium (Ho: µ1 = µ2) is 0.436 > 0.05. Then,
