ANSWER FAST PLS IM1 Unit 1 Standard 1 Homework #4

The shoe size for all the pairs of shoes in a person's closet are recorded below:

7,7,7,7,7,7,7,7,7,7

1) What is the mean? How do you know?

2) What is the standard deviation? How do you know?

Here is another data set:
1,2,3,3,4,4,4,4,5,5, 6, 7

3) What happens to the mean and standard deviation of the data set when the 7 is
changed to a 70? How do you know?

4) For the data set with the value of 70, why would the median be a better choice
for the measure of center than the mean?

5) Looking at the data set below, what effect does eliminating the highest value,
180, from the data set have on the mean, median, and standard deviation?
25, 50, 50, 60, 70, 85, 85, 90, 90, 180

6) A reporter counts the number of times a politician talks about jobs in their
campaign speeches.

7) What is a more accurate value for the standard deviation 1.4, 3.1, or 5.6? How do
you know?

Step-by-step explanation:

wow

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

"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).
