WebFor 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. WebSuccess/Failure Condition: If we expect at least 10 successes (np ≥ 10) and 10 failures (nq ≥ 10), then the binomial distribution can be considered approximately Normal. (Note that some texts require only five successes and failures.) Remember, students need to check this condition using the information given in the problem. inbound bpo https://charlotteosteo.com

WebNormality test. In statistics, normality tests are used to determine if a data set is well-modeled by a normal distribution and to compute how likely it is for a random variable underlying the data set to be normally distributed.
