Which of the following best describes the meaning behind the area under the probability density function's smooth curve? a. The number of observations between a specified range of outcomes b. The standard deviation of the distribution c. The shape and spread of the distribution d. The probability associated with the specified range of outcomes
Added by Timothy C.
Step 1
The area under the curve represents the probability of an observation falling within a specified range, not the number of observations. b. The standard deviation is a measure of the spread of the distribution, but it is not represented by the area under the Show more…

Which of the following is not a characteristic of the normal probability distribution? a. The graph of the curve is the shape of a rectangle b. The total area under the curve is always equal to 100%. c. 99.72% of the time the random variable assumes a value within plus or minus three standard deviations of its mean d. The mean is equal to the median, which is also equal to the mode.
