: Which one of the following statements is True? The units of the Variance are the same as the original data. The Mean can be found from a Box Plot. Relative Frequency equals Frequency multiplied by Total Frequency. An Ogive chart increases in height from left to right. For a unimodal mound shaped distribution that is Skewed Left the Mean is greater than the Median.
The following data show the monthly rental price (in $) for a random sample of one- bedroom apartments in York, Pennsylvania: 600 760 660 755 675 780 755 615 Suppose that the Mean of the monthly rental price or one-bedroom apartment in York, Pennsylvania is 700 (x = 700) Fill in the blank by selecting the correct answer from the drop list box The Median of the monthly rental price for one-bedroom apartment in York, Pennsylvania is • The Variance of the monthly rental price for one-bedroom apartment in York, Pennsylvania is • Noting that the sample standard deviation of monthly rental price for one-bedroom apartment in York, Pennsylvania is 71.21, then by using the Empirical Rule, represents the 95.4% interval for the monthly rental price The coefficient of variation of this data is
Select all true statements below (Multiple or none can be true). With a large, representative sample, the histogram of the sample data will follow the normal curve closely. If two lists of numbers have exactly the same average of 50 and SD of 10, then the percentage of entries between 40 and 60 must be exactly the same for both lists. Half of a list of numbers is always below its average. The median and average of a list of numbers are not necessarily close together.

Corporate Farms. The U.S. Census Bureau estimates the mean value of the land and buildings per corporate farm. Those estimates are published in the Census of Agriculture. Suppose that an estimate, x, is obtained and that the margin of error is $1000. Does this result imply that the true mean, μ, is within $1000 of the estimate? Explain your answer.
