This function tests the null hypothesis that a sample comes from a normal distribution. It is based on D’Agostino and Pearson’s [1], [2] test that combines skew and kurtosis to produce an omnibus test of normality. The array containing the sample to be tested. lawnscape well

WebUsing the calculator above, you find that a difference in sample proportions of 3% [3% = 20% - 17%] would results in a z-score of 2.73 under the null distribution, which translates to a p-value of 0.63%. Interpret Your Results - Since your p-value of 0.63% is less than the significance level of 5%, you have sufficient evidence to reject the ... WebMake a decision to accept or reject the omnibus hypothesis (Ho). The probability (0. 005) calculated with the test statistic (F = 3. 726) is less than alpha (0. 05), so we reject the null hypothesis (Ho). Example 2 • Example 2 5.
