When n-1 is used in the denominator to compute variance
the data set is a sample.
the data set is a population.
the data set could be either a sample or a population.
the data set is from a census.

rk (Copy) Score: 0.5 of 1 pt 23 of 35 (21 complete) 2.4.7 Discuss the similarities and the differences between the Empirical Rule and Chebychev's Theorem What is a similarity between the Empirical Rule and Chebychev's Theorem? A. Both do not require the data to have a sample standard deviation. B. Both estimate proportions of the data contained within k standard deviations of the mean. C. Both calculate the variance and standard deviation of a sample. O D. Both apply...

According to Chebyshev's Theorem, for any distribution, at least what proportion of data are within k=2.5 standard deviations of the mean? Round your answer to the nearest whole number.
Need help on how to do question 7! MTH 243 2.5 The Empirical Rule and Chebyshev's Theorem-Saylor 6. A population data set with a bell shaped distribution has mean p-6 and standard deviation ơ-2. Find the approximate proportion of observations in the data set that lie: a. between 4 and 8 b. between 2 and 10; c. between 0 and 12. 7. A population data set with a bell-shaped distribution has mean -2 and standard deviation a -1.1. Find the...
A balanced coin is tossed three times. Let Y equal the number of heads observed. (a) Use the formula for the binomial probability distribution to calculate the probabilities associated with Y = 0, 1, 2, and 3. PCY = 0) = P(Y = 1) = PLY = 2) = P(Y = 3) = (b) Construct the probability distribution below. ply) (c) Find the expected value and standard deviation of y, using the formulas E(Y) = np and V(Y) = npq....

b) If the sample size is 150, by Chebyshev's rule, at least how many measurements are in the interval within two SDV of the mean? Show your reason or work. c) If the sample size is 150 and we assume the data set is mound shaped, by empirical rule, approximately how many measurements is beyond the interval two SDV of the mean? Show your reason or work. That means, they are either belowor above
Use the empirical rule to solve the problem. A data set has size 70. Approximately how many observations lie within 2 standard deviations to either side of the mean? Explain please
