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:

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

The correct option for this case is:

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

Daniel [21]

Answer:

$513.34

Step-by-step explanation:

Mr. DeLuca used his debit card twice, each time for $27.50. This is a total of $55 spent.

$27.50 × 2 = $55

You now have to subtract the money spent from his bank balance.

$568.34 - $55 = $513.34

$513.34 was left in his bank account.

Please help! 15 points! Do not steal or I will report!

igomit [66]

Answer:

$\sqrt{ 384}$

Step-by-step explanation:

Well I commented this already but I'm not sure if you saw it. If you're trying to convert it all to a radical form then you square the 8 and multiply it by the 6.

$8 \sqrt{6}$

8² = 64

64 • 6 = 384

$\sqrt{ 384}$
