A student was studying the political party preferences of a university's student population. The survey instrument asked students to identify their political preference, for example, Conservatives, Liberals, NDP, Green Party, and other parties. The best way to illustrate the frequencies for each political preference is a Multiple Choice O Box plot O Bar chart O Histogram O Frequency polygonWhat is a disadvantage of the range as a measure of dispersion? Multiple Choice O It can be distorted by the outliers. O It can be distorted by a large mean. O It is not in the same units as the original data. O It has no specific disadvantage.According to Chebyshev's theorem, at least what percent of the observations lie within plus and minus 1.5 standard deviations of the mean? Multiple Choice O 95% O 56% O 67% O 86%The test scores for a class of 149 students are collected. What is the location of the test score associated with the 6th decile? Multiple Choice O 90 O 25 O 60% O 14.90According to the central limit theorem, Multiple Choice O the population mean and the mean of all sample means are equal O the sampling distribution of the sample means is approximately normally distributed O increasing sample size decreases the dispersion of the sampling distribution O the sampling distribution of the sample means will be skewedA random sample of 20 Alacoma patients show that 20% of them suffer from internal bleeding. But the statistician in charge of study complaints that she is not able to construct confidence interval for the population proportion, because: Multiple Choice O n(1-P)
