The path a character takes to navigate a level of a video game is given in the following graph.
1 answer:
The domain is the set of x values that has a corresponding y-values in a function or a graph.
The domain of the graph is:
From the graph (see attachment), we have the following observation
- The value of x starts from -10 (represented by the horizontal line from (-10,4) to (-4,4))
- The value x ends at 10 (represented by the slant line on the first quadrant)
These values can be represented as:
So, the domain of x is:

Answer:
There is no sufficient evidence to conclude that population mean number of times that adults go out for dinner each week is less than 1.5
Step-by-step explanation:
From the question we are told that
The population mean is less than 1.5
The sample size is n = 7
The sample data is 2, 0, 1, 5, 0, 2, and 3
Generally the sample mean is mathematically represented as
=>
=>
Generally the standard deviation is mathematically represented as
=>
=>
The null hypothesis is
The alternative hypothesis is
Generally the test statistics is mathematically represented as
=>
=>
Generally the p-value is mathematically represented as
From the z-table
So
From the values obtained we see that
Here there is no sufficient evidence to conclude that population mean number of times that adults go out for dinner each week is less than 1.5
