Answer:
The data are at the
<u>Nominal</u> level of measurement.
The given calculation is wrong because average (mean) cannot be calculated for nominal level of measurement.
Step-by-step explanation:
The objective here is to Identify the level of measurement of the data, and explain what is wrong with the given calculation.
a)
The data are at the <u> Nominal </u> level of measurement due to the fact that it portrays the qualitative levels of naming and representing different hierarchies from 100 basketball, 200 basketball, 300 football, 400 anything else
b) We are being informed that, the average (mean) is calculated for 597 respondents and the result is 256.1.
The given calculation is wrong because average (mean) cannot be calculated for nominal level of measurement. At nominal level this type of data set do not measure at all , it is not significant to compute their average (mean).
congruent, vertical angles
Notice that in the chart, the 2 grey sections (slope and y-intercept) are the two numbers that we need in order to write our equation.
(CHART #1)
We know the slope and a point (x,y). We can use this information to solve for b. Then we can write our equation.
First we will substitute the information that we know (that is in our chart) into the equation, y = mx + b. Then you will solve for b. (CHART #2)
Now we know the slope (m) is -2 because that was given to us. We also now know the y-intercept (b), which is 9 because we just solved for b.
We can now write our equation!
m = -2
b = 9
y = mx + b
y = -2x + 9
Answer:
2
Step-by-step explanation:
The z-score is the number of standard deviations the value is above the mean. If that number is 2, then Z=2. If that number is -2, then Z=-2.
___
Both Z=2 and Z=-2 are values that are two standard deviations from the mean.
We have been provided a diagram which tells us that Patti drew vertical line segments from two points to the line in her scatter plot. The first point she selected was dwarf crocodile. The second point she selected was for an Indian Gharial crocodile.
We can see that dwarf crocodile's bite force is closer to line of best fit than Indian Gharial crocodile. Indian Gharial crocodile seems to be an outlier for our data set.
Therefore, Patti's line have resulted in a predicted bite force that was closer to actual bite force for the dwarf crocodile.
