Q1 = mean of 6 and 7 values

Answer from: KarenH3512

D. The mean of the 6th and 7th values.

Step-by-step explanation:

We have been given that there are 25 values in a data set in order from smallest to largest. We are asked to find the value of first quartile of the data set.

Since our given data set is odd numbered, so the median of the data set would be value of 13th data point.

To find the first quartile, we need to find the median of first half of data set that will be the average of 6th and 7th data point as we will not include 13 th data point.

Therefore, the option D is the correct choice.

"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).

step-by-step explanation:

75% of the temperatures are below what value? how do you know? 75% of the temperatures are above w
