View all of Khan Academy’s lessons and practice exercises on probability and statistics. For this example question the X-value is your SAT score, 1100. Step 2: Put the mean, μ, into the z-score equation. Step 3: Write the standard deviation, σ into the z-score equation. Step 4: Find the answer using a calculator: (1100 – 1026) / 209 = .354. This means that your score was .354 std devs above the mean.Step 2: State the Alternate Hypothesis. The claim is that the students have above average IQ scores, so: H 1: μ > 100. The fact that we are looking for scores “greater than” a certain point means that this is a one-tailed test. Step 3: Draw a picture to help you visualize the problem. Step 4: State the alpha level.a) The exact value is 982.98. b) No, the result from part (a) could not be the actual number of adults who said that they play football because a count of people must result in a whole number. c) The actual number of adults who play football could be 983. d) 40.73%.Our 1000+ Probability and Statistics MCQs (Multiple Choice Questions and Answers) focuses on all chapters of Probability and Statistics covering 100+ topics.
