Calculate the range, population variance, and population standard deviation for the following data set. If necessary, round to o
Roman55 [17]

Answer:

Range = 11-2=9

\mu = \frac{2+3+4+5+6+7+8+9+10+11}{10}=6.5

\sigma^2 =8.25 \approx 8.3

\sigma = \sqrt{8.25}= 2.87 \approx 2.9

Step-by-step explanation:

Assuming this question: "Calculate the range, population variance, and population standard deviation for the following data set. If necessary, round to one more decimal place than the largest number of decimal places given in the data. 2,3,4,5,6,7,8,9,10,11 "

Solution to the problem

The range is defined as Range = Max -Min and if we replace we got:

Range = 11-2=9

Now we can calculate the population mean with this formula:

\mu =\frac{\sum_{i=1}^n X_i}{N}

And if we replace we got:

\mu = \frac{2+3+4+5+6+7+8+9+10+11}{10}=6.5

The population variance is given by:

\sigma^2 = \frac{\sum_{i=1}^n (X_i -\mu)^2}{N}

And after replace we got: \sigma^2 =8.25 \approx 8.3

And the population standard deviation would be just the square root of the variance and we got:

\sigma = \sqrt{8.25}= 2.87 \approx 2.9

Nooooow this is the story all about how my life got flipped turned upsidedown and id like to take a minute so sit right there and ill tell you how i became the prince of a town called Bel Air.

In west Philadelphia born and raised on the playground is where i spent most of my days. chillin out maxin relaxin all cool and all shootin some b-ball outside of the school

when a couple of guys, they were up to no good, started making trouble in my neighborhood. i got in one little fight and my mom got scared she said "youre moving with your auntie and uncle in bel air"

i begged and pleaded with her day after day, but she packed my suit case and sent me on my way. she gave me a kiss and then gave me my ticket i put my walkman on and said "i might as well kick it."

first class yo, this is bad drinkin orange juice outta champagne glass is this what the people of bel air be livin like? hmmm this might be alright. but wait i hear theyre prissy, bourgeois, all that. is this the type of that they just send this cool cat?

i dont think so, ill see when im there. i hope theyre prepared for the prince of bel air. well the plane landed and when i came out there was a dude who looked like a cop standing there with my name. i aint trying to get arrested yet i just got here i sprang with the quickness like lightning, disappeared.

i whistled for a cab and when it came near the license plate said fresh and it had dice in the mirror. if anything i could say that this cab was rare. but i thought "nah forget it- yo homes to bel air!"

i pulled up to a house about 7 or 8 and i yelled to the cabbie "yo homes smell ya later!" i looked up at my kingdom, i was finally there. to sit on my throne as the prince of bel air.
