Which of the following statments is TRUE?Both a bar chart and a box&whiskers plot can be used to represent qualitative data.Scatter plots can be used to represent qualitative and quantitative data both:Quantitative data. can be represented on histograms or on a box&whiskers plot.On a box&whiskefs plot the box contains the proportion of those observations which are within one standard deviation of the mean. Which of the following statments is TRUE? The statistical power of a. test increases if (ceteris paribus)..the effect size decreases, the probability of type I error decreases or the sample size decreasesthe effect size increases, the probability of type I error increases or the sample size increasesthe effect size increases, the probability of type I error decreases or the sample size increasesthe effect size decreases, the probability of type I error increases or the sample size decreases Let α denote the probability of making a type I error and ß the probability of making a type II error. Which of the following statments is TRUE?The statistical power of a test equals to 1 — α.The probability of rejecting a true nuflhypothesis equals 1 — ß.The probability of rejecting a false nullhypothesis 15 also known as the statistical power of the test.The probability of not rejecting a false nullhypothesis equals to α. We calculated the Mahalanobis distance of all 28 metric variables and found that the largest value belongs to Oman With 2.20. What conclusions can be drawn?Based on the Mahalanobis distance measure no observations need to be removed from the dataset.Based on the Mahalanobis...
