# Victor collects data on the price of a dozen eggs at 8 different stores.median: \$ 1.55Find the lower quartile and upper quartile ofthe data set.lower quartile: \$upper quartile: S?\$1.39 \$1.40 \$1.44 \$1.50 \$1.60 \$1.63 \$1.65 \$1.80

Lower quartile: \$1.42

Upper quartile: \$1.64

Step-by-step explanation:

The median is the middle value when all data values are placed in order of size.

The ordered data set is:

\$1.39 \$1.40 \$1.44 \$1.50 \$1.60 \$1.63 \$1.65 \$1.80

There are 8 data values in the data set, so this is an even data set.

Therefore, the median is the mean of the middle two values:

Place "||" in the middle of the data set to signify where the median is:

\$1.39 \$1.40 \$1.44 \$1.50 ║ \$1.60 \$1.63 \$1.65 \$1.80

The lower quartile (Q₁) is the median of the data points to the left of the median.  As there is an even number of data points to the left of the median, the lower quartile is the mean of the the middle two values:

The upper quartile (Q₃) is the median of the data points to the right of the median.  As there is an even number of data points to the right of the median, the upper quartile is the mean of the the middle two values:

to find the lower quartile and upper quartile of the given dataset, we need to first arrange the data in ascending order:

\$1.39, 1.40, 1.44, 1.50, 1.60, 1.63, 1.65, 1.80\$

The median of the dataset is given as \$1.55\$. Since there are an even number of data points, the median is the average of the two middle values, which in this case are \$1.50\$ and \$1.60\$.

Now, we need to find the lower quartile and upper quartile. The lower quartile is the median of the lower half of the data set, and the upper quartile is the median of the upper half of the data set.

The lower half of the dataset is \$1.39, 1.40, 1.44, 1.50\$. The median of this half is the average of the middle two values, which are \$1.40\$ and \$1.44\$.

Therefore, the lower quartile is \$1.42\$.

The upper half of the dataset is \$1.60, 1.63, 1.65, 1.80\$. The median of this half is the average of the middle two values, which are \$1.63\$ and \$1.65\$.

Therefore, the upper quartile is \$1.64\$.

Hence, the lower quartile of the dataset is \$1.42\$ and the upper quartile is \$1.64\$.

Both the galapagos Islands and the island of naura are on the equator, but the galapagos Islands are at 90.30 degree West whereas the island of naura is at 166.56 degree east. How far is it from galapagos Islands to naura travelling over the pacific ocean along the equator, correct to the nearest km

11481.4875 km

Step-by-step explanation:

Given the that :

Galapagos island and Island of Naura are on the equator

Galapagos = 90.30°W

Island of Naura = 166.56°E

Ensuring same bearing is used for both :

Island of Naura = 166.56°E = (360° - 166.56°) = 193.44°W

Hence, we can calculate the difference in the bearing of both locations :

(193.44 - 90.30)°W = 103.14°

Hence the distance between Galapagos and Island of Naura along the equator is :

(Difference in bearing / total bearing) * earth's Circumference

Earth's Circumference = 40,075km

(103.14 / 360) × 40,075

0.2865 × 40,075

= 11481.4875 km
