3. A concert scheduled for May 24th is creating a difficult decision for the concert promoter. Her projections show that if the concert is held indoors, the profits will likely be $17,000. An outdoor concert is much more profitable. Without rain, an outdoor concert will bring profits of $74,000. However, with rain, an outdoor concert would probably lead to a loss of $157,000. Data of rain in May shows that there is a 0.21 probability of significant rain during the evening. What is the expected value of holding the outdoor concert? Should the promoter schedule the concert for indoors or outdoors?

1. why is a frequency distribution useful? it allows researchers to see the "shape" of the data. it tells researchers how often the mean occurs in a set of data. it can visually identify the mean. it ignores outliers. 2. the is defined by its mean and standard deviation alone. normal distribution frequency distribution median distribution marginal distribution 3. approximately % of the data in a given sample falls within three standard deviations of the mean if it is normally distributed. 95 68 34 99 4. a data set is said to be if the mean of the data is greater than the median of the data. normally distributed frequency distributed right-skewed left-skewed
