Given the conversion table of these data points of temperatures in Celsius and the respective value in Fahrenheit: C F 10 50 20 68 30 86. To calculate the mean in Celsius: xC¯ = 10 + 20 + 30 3 = 20. and standard deviation:
I'd like to know why. Method 1: Subtract 28 degrees celsius from 42 degrees celsius. Convert the resulting answer to fahrenheit. This method yields an answer of - 57.6 degrees celsius. Method 2: First convert 42 degrees celsius to fahrenheit. Then convert 28 degrees celsius to fahrenheit. Then find the difference of the resulting two numbers.
celsius=5/9(fahrenheit− 32) if the standard deviation of a random sample containing 14 people is 0.9 degrees farenheit, what's the variance in celsius? I have tried 5/9(0.18-32) but I get a negative number for variance which is obviously wrong. I used 0.18 because 0.9^2=0.18.
The Fahrenheit-Celsius conversion formula is $F= \frac{9}{5}C+32$. Suppose the temperature measured in Celsius has mean $\mu$ and variance $\sigma^2$.
The variance is in m2 m 2. If you want to convert a standard deviation in m to a variance in ft2 2, you can convert the std deviation to ft by multiplying by 3.28 3.28, then square to get the variance, or square and then multiply by 3.282 3.28 2 because you are converting m2 m 2 to ft2 f t 2. – Ross Millikan.

I summarize my two questions with this claim that a temperature increase of $1$ degree Fahrenheit is equivalent to a temperature increase of $\frac{5}{9}$ degree Celsius, and I want to determine whether it is true or false, but I don't understand what a temperature increase of $1$ degree Fahrenheit and a temperature increase of $\frac{5}{9 ...
This is the correct conversion when converting temperature changes. If the temperature today is 10 Celsius degrees higher than it was yesterday, then it is $10\cdot \frac{180}{100} = 18$ Fahrenheit degrees higher. A change of zero degrees Celsius is equal to a change of zero degrees Fahrenheit.
The addition or subtraction of 273.15 is not actually a unit conversion; it is a scale conversion. As units of heat, 1 degree Celsius = 1 Kelvin (and also, 9/5 degree Fahrenheit). Addition or subtraction enters the picture because when we measure actual temperatures, we do it relative to a base point that is different for each scale.
You might say that the standard deviation is a yardstick, and a z z -score is a measurement expressed in terms of that yardstick. The situation is a little different from simple conversion between inches and feet, though. It’s more like conversion between Fahrenheit and Celsius temperatures: not only does the size of the unit change, but also ...
One thing I can say for sure, regardless of which axis represents which variable, is that the graph should go through the point $(-40,-40)$, which your graph doesn't. The reason is that $-40$ is the (one and only) temperature that comes out the same on the Fahrenheit and Celsius scales.
