Answer:
β = (-0.19 dB).
Step-by-step explanation:
The formula which is used to calculate the decibel level of a sound is given by :
I is intensity of the sound of a ticking clock
watts per square meter
Since,
The intensity of a monster truck is converted into per square meter as follows:
So, Decibal level is :
So, the decibel level of the sound of a ticking clock is (-0.19 dB).
Answer:
a. Scatterplot is attached.
b. Positive Correlation
c. Correlation coefficient=0.9219
Step-by-step explanation:
a.
The following procedure will be used to obtain the scatter plot
A scatter plot visualizing your data should be displayed as attached.
b.
-From the trend line, your notice that your variables have a positive correlation.
-As the income increases, so does vacation expenditure.
c. The correlation coefficient can be calculated as follows.
-From our Google Sheets calculation our variables have a positive correlation and the correlation coefficient is 0.9219
-The correlation coefficient,r can also be calculated manually:
-let x be income, and y be vacation and divide all the values by 100 to make the smaller and easier to manipulate:
