Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (6, 5)

Point (5, 3)

Step 2: Find slope m

Substitute [SF]: $m=\frac{3-5}{5-6}$
Subtract: $m=\frac{-2}{-1}$

A restaurant decides to test their oven's thermostat to see if it is working properly, that is, if the actual temperature inside

Taya2010 [7]

Answer:

For this case we have information from a sample of n =20 times of temperatures of the oven

The parameter of interest is $\mu$ population temperature mean of the oven

And the statistic is calculated with this formula:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}$

With n = 20 and represent the mean temperature of the oven

The correct option for this case is:

mu = the true mean temperature of the oven xbar = the true mean temperature of the oven

Step-by-step explanation:

Previous concepts

Parameter represent a property of a population and is calculated with the information of all the populatio. Some examples are the population mean and deviation $\mu,\sigma$

Statistic represent a propoerty of a sample and are used used in order to describe the population parameters, since represent estimators of the real parameters.

Solution to the problem

For this case we have information from a sample of n =20 times of temperatures of the oven

The parameter of interest is $\mu$ population temperature mean of the oven

And the statistic is calculated with this formula:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}$

With n = 20 and represent the mean temperature of the oven

The correct option for this case is:

mu = the true mean temperature of the oven xbar = the true mean temperature of the oven
