NettetWhat is true with regard to both mound-shaped and uniform frequency distributions? Their histograms are not symmetrical. Both have more data values to one side of the mean than the other. Their histograms are symmetrical. The values of the mean, mode, and median are different.Data values are evenly distributed around the mean. NettetConsider that in 2024 US household income had a mean of $64,000, a standard deviation of $12,000, and a frequency distribution that was mound-shaped and symmetric. Using the Empirical Rule, determine the probability that someone selected at random will have a z-score less than 2.00. 0.02500.52500.95000.9750 NettetMound shaped distributions are very important because they frequently occur as population distribu-tions. Even more importantly, the central limit theorem says that if we take all samples of a given size from a population and calculate all of the means, then the distribution of the means is mound shaped (Normal). slow cookers 4.5 litres

Nettet26. mar. 2024 · Figure 2.5. 3: Distribution of IQ Scores. Since 68 % of the IQ scores lie within the interval from 90 to 110, it must be the case that 32 % lie outside that interval. By symmetry approximately half of that 32 %, or 16 % of all IQ scores, will lie above 110. If 16 % lie above 110, then 84 % lie below. slow cooker sachet mixNettetA numerical model was developed to simulate the evolution of a mound placed in the offshore (i.e., outside the zone of wave breaking), exposed to varying non-breaking waves and water levels.
