The linear regression model gives mathematical relationship between two variables, the dependent<em> and </em>independent<em> variables</em>. The linear models between the <em>quantity sold and the variables average price, disposable income and monthly advertising are</em> :

  • <em>y = - 4713.46x + 117763</em>
  • <em>y = 2.94x - 58384</em>
  • <em>y = - 1.75x - 32655</em>

To create a linear model using the data given, we use technology such as a excel or a linear regression calculator :

The linear model created using a linear regression calculator between each of the independent variables and quantity sold are :

<u>Average price of deep - dish and Quantity sold :</u>

  • Average price of deep - dish pizza(X)
  • Quantity sold (Y)

y = - 4713.46x + 117763

<u>Disposable income and Quantity sold</u> :

  • Disposable income (X)
  • Quantity sold (Y)

y = 2.94x - 58384

<u>Monthly advertising expenditure and Quantity sold</u> :

  • Monthly advertising cost (X)
  • Quantity sold (Y)

y = - 1.75x - 32655

The mass of a species of mouse commonly found in houses is normally distributed with a mean of 20.2 grams with a standard deviat
Sophie [7]

Answer:

12.1%

Step-by-step explanation:

Given that:

Mean (μ) = 20.2 grams and standard deviation (σ) = 0.18 grams.

The z score is a score used to determine the number of standard deviations by which the raw score is above or below the mean. A positive z score means  that the raw score is above the mean and a negative z score means that the raw score is below the mean. It is given by:

z=\frac{x-\mu}{\sigma}

a) For x < 19.99 g:

z=\frac{x-\mu}{\sigma}\\\\z=\frac{19.99-20.2}{0.18} \\\\z=-1.17

From the normal distribution table, P(x < 19.99) = P(z < -1.17) = 0.1210 = 12.1%

The probability that a randomly chosen mouse has a mass of less than 19.99 grams is 12.1%
