Prepare a Pareto chart of the possible causes for a student to fail a final examination in a university course.

Hitman42 [59]

Answer:

Option 1

$\bar x_1 = 96.2$

$Mode = 99$

$\sigma_1 = 3.22$

Option 2

$\bar x_2 = 97.4$

$Mode = 97$

$\sigma_2 = 0.499$

Explanation:

Given

$Option\ 1: 99, 98, 99, 94, 92, 99, 98, 99, 94, 90$

$Option\ 2: 98, 97, 97, 97, 98, 98, 97, 97, 98$

Required

The mean, mode and standard deviation of both options

Option 1

Calculate mean

$\bar x = \frac{\sum x}{n}$

$\bar x_1 = \frac{99+ 98+ 99+ 94+ 92+ 99+ 98+ 99+ 94+ 90}{10}$

$\bar x_1 = \frac{962}{10}$

$\bar x_1 = 96.2$

Calculate mode

$Mode = 99$

Because it has a frequency of 4 (more than other element of the dataset)

Calculate standard deviation

$\sigma = \sqrt{\frac{\sum(x - \bar x)^2}{n}}$

$\sigma_1 = \sqrt{\frac{(99-96.2)^2 +.............+(90-96.2)^2}{10}}$

$\sigma_1 = \sqrt{\frac{103.6}{10}}$

$\sigma_1 = \sqrt{10.36}$

$\sigma_1 = 3.22$

Option 2

Calculate mean

$\bar x = \frac{\sum x}{n}$

$\bar x_2 = \frac{98+ 97+ 97+ 97+ 98+ 98+ 97+ 97+ 98}{9}$

$\bar x_2 = \frac{877}{9}$

$\bar x_2 = 97.4$

Calculate mode

$Mode = 97$

Because it has a frequency of 5 (more than other element of the dataset)

Calculate standard deviation

$\sigma_2 = \sqrt{\frac{(98-97.4)^2+..............+ (98-97.4)^2}{9}}$

$\sigma_2 = \sqrt{\frac{2.24}{9}}$

$\sigma_2 = \sqrt{0.2489}$

$\sigma_2 = 0.499$

Taya2010 [7]

Answer:

Time value of money

Explanation:

This principle states that money is more valuable at the moment or present than same amount of money in the future due its potential for increase in profit. A person or an investor that wants to make a return or gain will prefer to have the money now than have the same amount of money in the future. This is due to the potential of the money to increase in terms of earning capacity.
