Use the data from problem:

navik [9.2K]

Answer:

a) Sample mean: 48.71

Sample median: 48.3

Sample variance: 5.41

Sample standard deviation: 2.37

Step-by-step explanation:

a) Sample mean:

$\bar{X}=\frac{1}{N} \sum X_i=\frac{1}{80}*3896.9=48.71$

Sample median: M=48.3

Note: I order the data increasingly and take the value N / 2 = 40. In this way there are 39 values above and 39 values below the median.

Sample variance:

$s^2=\frac{1}{N-1}\sum (X_i-\bar X)^2 =(\frac{1}{80-1})*427.74=5.41$

Sample standard deviation

$s=\sqrt{s^2}=\sqrt{5.41}=2.37$

A group of adults and students went on a class trip to Washington, DC. The number of male students was 1 more than 7 times the n

AVprozaik [17]

X number of male students
Y number of female students
Z number of the adults
X=(1 + 7)Z=8Z
Y= X/2
X +Y +Z = 82
8Z +8Z/2 +Z=82 implies Z=82/26=3.1
so we take Z= 3

X= 24
and Y = 12

Vilka [71]

Answer:

Number of years between 1950 and 2100 =

$2100 - 1950 = 150 \: years$

150 = 50 + 50 + 50 years.

$2500000 \times 150 = 375,000,000$

So, total population in 2100 is 375,000,000.
