The graduate management admission test (gmat) is a standardized exam used by many universities as part of the assessment for admission to graduate study in business. the average gmat score is 547 (magoosh website, january 5, 2015). assume that gmat scores are bell-shaped with a standard deviation of 100. make sure to use the empirical rule to answer these questions. a. what percentage of gmat scores are 647 or higher?

16% of GMAT scores are 647 or higher.

Step-by-step explanation:

Consider the provided information.

The average GMAT score is 547. Assume that GMAT scores are bell-shaped with a standard deviation of 100.

We need find the percentage of GMAT scores are 647 or higher.

Substitute the respective values in above formula.

According to the empirical rule 68% will fall within the first standard deviation.

100 - 68 = 32% of the provided data fall outside the first standard deviations of the mean. Also = 16% of the provided data fall below the first standard deviations of the mean.

Therefore, 16% of GMAT scores are 647 or higher.

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
