We want to know if there is a difference between the mean list price of a three bedroom home, , and the mean list price of a fou

Answer:
The alternative hypothesis will state that there is significant difference between the mean list price of a three bedroom home and the mean list price of a four bedroom home.
Step-by-step explanation:
This would be an two-sample hypothesis test for the difference between two means.
As we are looking for differences, we are not testing if one population mean is bigger than the other. This will be a two-tailed test and the alternative hypothesis will have a unequal sign.
The alternative hypothesis will state that there is significant difference between the mean list price of a three bedroom home and the mean list price of a four bedroom home.
This can be written as:
meaning that the population means are significantly different.

Answer:
Step-by-step explanation:
The given function is .
If an exponential function is of the form; , then
will vertically shrink the base function
and will vertically stretch the graph by
units.
The correct answer is B.
Answer:
Range = (-<em>∞, 5</em>)
Step-by-step explanation:
This is the absolute value function with transformation.
The parent function is f(x) = |x|
This function has a "negative" in front, so it makes it reflect about x axis
The -4 after x makes horizontal translation of 4 units right
the +5 at the end makes the function translate 5 units UP
<em>The graph is shown in the attached picture.</em>
<em>Looking at the graph, we can clearly see the range. The range is the allowed y-values. Hence, we can see that the </em><em>range is -infinity to 5</em>

The probability that you'll be a magic elf is or 6.66%.
Step-by-step explanation:
Step 1:
Let A be the event of you choosing an elf.
The probability of an event is given by dividing the number of favorable outcomes by the total number of outcomes.
Here the number of favorable outcomes is 1 and the total number of outcomes is 3 i.e. elf, hobbit or human.
The probability of choosing an elf,
Step 2:
Let B be the event of you choosing magic as your defense.
In this situation, the number of favorable outcomes is 1 and the total number of outcomes is 5 i.e. magic, sword, shield, slingshot, or umbrella.
The probability of choosing magic as your defense,
Step 3:
The probability of both events A and B happening, we multiply the individual probabilities.
