The following are the last 7 days adjusted closing stock prices (in $) for Citigroup: 22, 25, 20, 15, 40, 55, 28 A) Compute the
son4ous [18]

Answer:

(A) The 25th percentile is 20.

(B) The mean of the data set is 20 and the median of the data set is 25. The data set is left-skewed.

Step-by-step explanation:

The data set arranged in ascending order is:

S = {15, 20, 22, 25, 28, 40, 55}

(A)

Compute the 25th percentile as follows:

25^{th} \text{Percentile}=[\frac{n+1}{4}]^{th}obs.\\\\=[\frac{7+1}{4}]^{th}obs.\\\\=2^{nd}obs.\\\\=20

Thus, the 25th percentile is 20. This value implies that exactly 25% of the observations are less than 20.

(B)

Compute the sample mean as follows:

\text{Mean}=\frac{22+25+20+15+40+55+28}{7}=\frac{205}{7}=29.29

Compute the median as follows:

For a set with odd number of observations, the median value if the middle value.

The middle value is 25.

Thus, the mean of the data set is 20 and the median of the data set is 25.

The Mean < Median.

This implies that the data set is left-skewed.

Earl wants to earn enough money to purchase a bike that costs $515. For every lawn he mows he earns $25 and then gets a daily bo
inysia [295]

Answer:

18 lawns

Step-by-step explanation:

Expected sum = $515

Bonus for 1 day = $15

Bonus for 5 days = $15 × 5 = $75

Amount to be earned from mowing lawns in 5 days = $515 - $75 = $440

$25 ≡ 1 lawn

$440 ≡ 440 ÷ 25 = 17.6

The minimum number of lawns is 18.

<em>(Note that we take the minimum integer greater than 17.6. If he mows 17 lawns, his earning from 17 lawns = $425 + $75 = $500)</em>
