All of the other options are false statements. |
All of the other options are false.
Deacause both mean,median,mode are measured of central tendency. That is all compute middel of data set.

Exactly two-thirds of all possible observed values of the random variable x are within plus or minus one standard deviations of the population meanC. The mean, median and mode are equalD. The area under the normal curve to the right of the mean is equal to the area under the normal curve to the left of the meanE. All of the...
Which of the following statements are TRUE? There may be more than one correct answer; select all that are true. A standard normal random variable cannot take on negative values. The normal distribution is symmetric about the mean mu. A normal distribution cannot have a negative mean. In a normal distribution, the mean and median are equal. If Z is a standard normal random variable, then P(Z > 41278) is very close to 0.
WHICHI OT the following statements is not true concerning the attributes of z-scores? A) z-scores are positive for data values above the mean of the distribution. B) 2-scores are negative for data values below the mean of the distribution. C) 2-scores indicate how many standard deviations an observation is away from the me D) z-scores are equal to zero for data values equal to the mean of the distribution. E) none of the above

10. Calculating the mean, median, and mode when scores are changedor removed Consider the following sample set of scores. Assume these scores are from a discrete distribution. 1 22 40 45 45 52 60 69 81 94 For the given data, the mean is , the median is ▼ , and the mode is Suppose the score 1 in the data is mistakenly recorded as 21 instead of 1. For the sample with this error, the mean is the median...
